Therefore we ought, etc. He now declares what he had before in view, by comparing Christ with angels, even to secure the highest authority to his doctrine. For if the Law given through angels could not have been received with contempt, and if its transgression was visited with severe punishment, what is to happen, he asks, to the despisers of that gospel, which has the Son of God as its author, and was confirmed by so many miracles? The import of the whole is this, that the higher the dignity of Christ is than that of angels, the more reverence is due to the Gospel than to the Law. Thus he commends the doctrine by mentioning its author. But should it seem strange to any one, that as the doctrine both of the Law and of the Gospel is from God, one should be preferred to the other; inasmuch as by having the Law lowered the majesty of God would be degraded; the evident answer would be this, -- that he ought indeed always to be heard with equal attention whenever he may speak, and yet that the fuller he reveals himself to us, it is but right that our reverence and attention to obedience should increase in proportion to the extent of his revelations; not that God is in himself less at one time than at another; but his greatness is not at all times equally made known to us. Here also another question arises. Was not the Law also given by Christ? If so, the argument of the Apostle seems not to be well grounded. To this I reply, that in this comparison regard is had to a veiled revelation on one side, and to that which is manifest on the other. Now, as Christ in bringing the Law showed himself but obscurely or darkly, and as it were under coverings, it is nothing strange that the Law should be said to have been brought by angels without any mention being made of his name; for in that transaction he never appeared openly; but in the promulgation of the Gospel his glory was so conspicuous, that he may justly be deemed its author. Lest at any time we should let them slip, or, "lest we should at any time flow abroad," or, if you prefer, "let dip," though in reality there is not much difference. The true sense is to be gathered from the contrast; for to give heed, or to attend and to let slip, are opposites; the first means to hold a thing, and the other to let off like a sieve, or a perforated vessel, whatever may be poured into it. I do not indeed approve of the opinion of those who take it in the sense of dying, according to what we find in 2 Samuel 15:14, "We all die and slide away like water." On the contrary, we ought, as I have said, to regard the contrast between attention and flowing out; an attentive mind is like a vessel capable of holding water; but that which is roving and indolent is like a vessel with holes.

Therefore - Greek "On account of this" - Δια τοῦτο Dia touto - that is, on account of the exalted dignity and rank of the Messiah as stated in the previous chapter. The sense is: "Since Christ, the author of the new dispensation, is so far exalted above the prophets, and even the angels, we ought to give the more earnest attention to all that has been spoken."
We ought - It is suitable or proper (Greek δεὶ dei) that we should attend to those things. When the Son of God speaks to people, every consideration makes it appropriate that we should attend to what is spoken.
To give the more earnest heed. - To give the more strict attention.
To the things which we have heard. - Whether directly from the Lord Jesus, or from his apostles. It is possible that some of those to whom the apostle was writing had heard the Lord Jesus himself preach the gospel: others had heard the same truths declared by the apostles.
Lest at any time. - We ought to attend to those things at all times. We ought never to forget them; never to be indifferent to them. We are sometimes interested in them, and then we feel indifferent to them; sometimes at leisure to attend to them, and then the cares of the world, or a heaviness and dullness of mind, or a cold and languid state of the affections, renders us indifferent to them, and they are suffered to pass out of the mind without concern. Paul says, that this ought never to be done. At no time should we be indifferent to those things. They are always important to us, and we should never be in a state of mind when they would be uninteresting. At all times; in all places; and in every situation of life, we should feel that the truths of religion are of more importance to us than all other truths, and nothing should be suffered to efface their image from the heart.
We should let them slip. - Margin, "Run out as leaking vessels." Tyndale renders this, "lest we be spilt." The expression here has given rise to much discussion as to its meaning; and has been very differently translated. Doddridge renders it, "lest we let them flow out of our minds." Prof. Stuart, "lest at any time we should slight them." Whitby: "that they may not entirely slip out of our memories." The word used here - παραῤῥυέω pararrueō - occurs nowhere else in the New Testament. The Septuagint translators have used the word only once. Proverbs 3:21. "Son, do not pass by (μὴ παραῤῥυῇς mē pararruēs but keep my counsel;" that is, do not pass by my advice by neglect, or suffer it to be disregarded. The word means, according to Passow, to flow by, to flow over; and then to go by, to fall, to go away. It is used to mean to flow near, to flow by - as of a river; to glide away, to escape - as from the mind, that is, to forget; and to glide along - as a thief does by stealth. See Robinson's Lexicon. The Syriac and Arabic translators have rendered it: "that we may not fall." After all that has been said on the meaning of the word here (compare Stuart in loc.), it seems to me that the true sense of the expression is that of flowing, or gliding by - as a river; and that the meaning here is, that we should be very cautious that the important truths spoken by the Redeemer and his apostles should not be suffered to "glide by" us without attention, or without profit. We should not allow them to be like a stream that glides on by us without benefiting us; that is, we should endeavor to secure and retain them as our own. The truth taught, is that there is great danger, now that the true system of religion has been revealed, that it will not profit us, but that we shall lose all the benefit of it. This danger may arise from many sources - some of which are the following:
(1) We may not feel that the truths revealed are important - and before their importance is felt, they may be beyond our reach. So we are often deceived in regard to the importance of objects - and before we perceive their value they are irrecoverably gone. So it is often with time, and with the opportunities of obtaining an education, or of accomplishing any object which is of value. The opportunity is gone before we perceive its importance. So the young suffer the most important period of life to glide away before they perceive its value, and the opportunity of making much of their talents is lost because they did not embrace the suitable opportunities.
(2) by being engrossed in business. We feel that that is now the most important thing. That claims all our attention. We have no time to pray, to read the Bible, to think of religion, for the cares of the world engross all the time - and the opportunities of salvation glide insensibly away, until it is too late.
(3) by being attracted by the pleasures of life. We attend to them now, and are drawn along from one to another, until religion is suffered to glide away with all its hopes and consolations, and we perceive, too late, that we have let the opportunity of salvation slip forever. Allured by those pleasures, the young neglect it; and new pleasures starting up in future life carry on the delusion, until every favorable opportunity for salvation has passed away.
(4) we suffer favorable opportunities to pass by without improving them. Youth is by far the best time, as it is the most appropriate time, to become a Christian - and yet how easy is it to allow that period to slip away without becoming interested in the Saviour! One day glides on after another, and one week, and one month, one year passes away after another - like a gently-flowing stream - until all the precious time of youth has gone, and we are still not Christians. So a revival of religion is a favorable time - and yet many suffer this to pass by without becoming interested in it. Others are converted, and the heavenly influences descend all around us, but we are unaffected, and the season so full of happy and heavenly influences is gone - to return no more.
(5) we let the favorable season slip, because we design to attend to it at some future period of life. So youth defers it to manhood - manhood to old age - old age to a death-bed - and then neglects it - until the whole of life has glided away, and the soul is not saved. Paul knew man. He knew how prone he was to let the things of religion slip out of the mind - and hence, the earnestness of his caution that we should give heed to the subject now - lest the opportunity of salvation should soon glide away. When once passed, it can never be recalled. Hence, learn:
(1) the truths of religion will not benefit us unless we give heed to them. It will not save us that the Lord Jesus has come and spoken to people, unless we are disposed to listen. It will not benefit us that the sun shines, unless we open our eyes. Books will not benefit us, unless we read them; medicine, unless we take it; nor will the fruits of the earth sustain our lives, however rich and abundant they may be, if we disregard and neglect them. So with the truths of religion. There is truth enough to save the world - but the world disregards and despises it.
(2) it needs not great sins to destroy the soul. Simple "neglect" will do it as certainly as atrocious crimes. Every person has a sinful heart that will destroy him unless he makes an effort to be saved; and it is not merely the great sinner, therefore, who is in danger. It is the man who "neglects" his soul - whether a moral or an immoral man - a daughter of amiableness, or a daughter of vanity and vice.

Therefore - Because God has spoken to us by his Son; and because that Son is so great and glorious a personage; and because the subject which is addressed to us is of such infinite importance to our welfare.
We ought to give the more earnest heed - We should hear the doctrine of Christ with care, candour, and deep concern.
Lest at any time we should let them slip - Μη ποτε παραρῥυωμεν· "Lest at any time we should leak out." This is a metaphor taken from unstanch vessels; the staves not being close together, the fluid put into them leaks through the chinks and crevices. Superficial hearers lose the benefit of the word preached, as the unseasoned vessel does its fluid; nor can any one hear to the saving of his soul, unless he give most earnest heed, which he will not do unless he consider the dignity of the speaker, the importance of the subject, and the absolute necessity of the salvation of his soul. St. Chrysostom renders it μη ποτε απολωμεθα, εκπεσωμεν, lest we perish, lest we fall away.

Therefore (1) we ought to give the more earnest heed to the things which (a) we have heard, lest at any time we (b) should let [them] slip.
(1) Now pausing to show to what end and purpose all these things were spoken, that is, to understand by the excellency of Christ above all creatures, that his doctrine, majesty and priesthood, is most perfect, he uses an exhortation taken from a comparison.
(a) He makes himself a hearer.
(b) They are said to let the word run out, who do not hold it securely and remember the word when they have heard it.

Therefore we ought to give the more earnest heed,.... This is an inference from the apostle's discourse in the preceding chapter; since he, by whom God has spoke in these last days, is his Son, who is infinitely above the angels, they being his creatures, and worshippers of him, and ministers to him, and his; therefore the greater regard should be had to the Gospel spoken by him: even to the things which we have heard; which are no other than the truths of the Gospel, which had been preached unto them, and which were heard by the apostles, who had preached them to them; and they had heard them from them, or from Christ himself, and were what their forefathers had desired to hear, and which the carnal ear has not heard; for there is an internal and an external hearing of the Gospel. Now it becomes the hearers of it to give heed, or attend unto it, to beware of that which is pernicious and hurtful, and to regard that which is good and profitable; and this giving heed takes in a close consideration of Gospel truths, a diligent inquiry into them, a valuable esteem of them, a strict adherence to them, and a watchfulness to retain what is heard, and to conform unto it: and this was to be done "more earnestly" than their forefathers had, or than they themselves had; or this may be put for the superlative degree, and signify, that they should give the most earnest heed; for they had the most abundant reason to give heed, since what they heard was not from Moses, and the prophets, to whom they did well to take heed, but from Christ the Son of God, who was greater than they: "lest at any time we should let them slip": and this either respects persons; and so the Vulgate Latin version renders it, "lest we should run out"; and the Syriac version, "lest we should fall"; and the Arabic version, "lest we should fall from honesty": which may intend partial slips and falls, to which the people of God are subject; and which are oftentimes owing to inadvertency to the word; for the Gospel, duly attended to, is a preservative from falling: or it may respect things, even the doctrines of the Gospel, lest we should let them slip out of us, through us, or besides us: the metaphor seems to be taken either from leaking vessels, which let out what is put into them; or to strainers, which let the liquor through, and it falls on the ground, and cannot be gathered up, and so becomes useless; and which is expressive of unprofitable hearing of the word, through inattention, negligence, and forgetfulness, and the irrecoverableness of it, when it is gone: the Gospel may be lost to some that hear it, as to any real benefit and advantage by it; and some who hear the Gospel may be lost and perish; but the grace of the Gospel can never be lost.

Christ being proved to be superior to the angels, this doctrine is applied. Our minds and memories are like a leaky vessel, they do not, without much care, retain what is poured into them. This proceeds from the corruption of our nature, temptations, worldly cares, and pleasures. Sinning against the gospel is neglect of this great salvation; it is a contempt of the saving grace of God in Christ, making light of it, not caring for it, not regarding either the worth of gospel grace, or the want of it, and our undone state without it. The Lord's judgments under the gospel dispensation are chiefly spiritual, but are on that account the more to be dreaded. Here is an appeal to the consciences of sinners. Even partial neglects will not escape rebukes; they often bring darkness on the souls they do not finally ruin. The setting forth the gospel was continued and confirmed by those who heard Christ, by the evangelists and apostles, who were witnesses of what Jesus Christ began both to do and to teach; and by the gifts of the Holy Ghost, qualified for the work to which they were called. And all this according to God's own will. It was the will of God that we should have sure ground for our faith, and a strong foundation for our hope in receiving the gospel. Let us mind this one thing needful, and attend to the Holy Scriptures, written by those who heard the words of our gracious Lord, and were inspired by his Spirit; then we shall be blessed with the good part that cannot be taken away.

DANGER OF NEGLECTING SO GREAT SALVATION, FIRST SPOKEN BY CHRIST; TO WHOM, NOT TO ANGELS, THE NEW DISPENSATION WAS SUBJECTED; THOUGH HE WAS FOR A TIME HUMBLED BELOW THE ANGELS: THIS HUMILIATION TOOK PLACE BY DIVINE NECESSITY FOR OUR SALVATION. (Hebrews. 2:1-18)
Therefore--Because Christ the Mediator of the new covenant is so far (Hebrews 1:5-14) above all angels, the mediators of the old covenant.
the more earnest--Greek, "the more abundantly."
heard--spoken by God (Hebrews 1:1); and by the Lord (Hebrews 2:3).
let them slip--literally "flow past them" (Hebrews 4:1).

Therefore we ought to give the more earnest heed. Because the message to us is spoken, not by angels or prophets, but by the Son of God.
To the things which we have heard. To Christ's gospel, and to his words of instruction.
Lest . . . we should let them slip. Lest we should let them slip from us because we drift away from them and refuse to heed them.
For if the word spoken by angels. The Jewish law. See notes on Acts 7:53 and Galatians 3:19. The law was given through the medium of angels, as was confessed by the Jews. See Josephus, Antiq. XV: 5, section 3.
Was steadfast. Confirmed by a penalty upon transgressors.
Every transgression. Nothing is plainer in all Jewish history than that obedience to the law was rewarded and disobedience punished.
How shall we escape. How then, if this was true of the law, can we hope to escape if he neglect the message of the Son?
So great salvation. Not a temporal, but an eternal salvation, the salvation of the gospel.
Begun to be spoken by the Lord. More especially after his death and resurrection when he bade his disciples go into all the world and preach the gospel to every creature.
Was confirmed to us. If Paul was the writer of Hebrews he places himself in the position of the church, for elsewhere he tells us plainly that he received the gospel from the Lord himself. The apostles who had heard and seen the risen Christ first proclaimed his gospel publicly on Pentecost, an event evidently alluded to in this passage.
God bearing them witness. God bore witness to the truth of their words by the signs and wonders of Pentecost. He also bore witness afterwards by giving them miraculous powers, and by the extraordinary gifts of the Holy Spirit. Note that when he Law was given on Sinai God bore witness by signs and wonders. Also when the gospel, the message of Christ, was given on Mt. Zion God bore witness with signs and wonders.

Lest we should let them slip - As water out of a leaky vessel. So the Greek word properly signifies.
