But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.

but exhort one another day by day, so long as it is called To-day; lest any one of you be hardened by the deceitfulness of sin:

But exhort one another every day, whilst it is called to day, that none of you be hardened through the deceitfulness of sin.

But encourage yourselves each day, as long as it is called To-day, that none of you be hardened by the deceitfulness of sin.

but exhort ye one another every day, while the To-day is called, that none of you may be hardened by the deceitfulness of the sin,

On the contrary encourage one another, day after day, so long as To-day lasts, so that not one of you may be hardened through the deceitful character of sin.

But give comfort to one another every day as long as it is still Today; so that no one among you may be made hard by the deceit of sin:

Instead, exhort one another every day, while it is still called 'today,' so that none of you may become hardened through the falseness of sin.

Rather encourage one another daily – while there is a today – to prevent anyone among you from being hardened by the deceitfulness of sin.

Sed exhortamini vos ipsos quotidie, quandiu vocatur dies hodiernus; nequis ex vobis induretur deceptione peccati.

He also pointed out the remedy, so that they might not fall into this wickedness, and that was, to exhort one another. For as by nature we are inclined to evil, we have need of various helps to retain us in the fear of God. Unless our faith be now and then raised up, it will lie prostrate; unless it be warmed, it will be frozen; unless it be roused, it will grow torpid. He would have us then to stimulate one another by mutual exhortations, so that Satan may not creep into our hearts, and by his fallacies draw us away from God. And this is a way of speaking that ought to be especially observed; for we fall not immediately by the first assault into this madness of striving against God; but Satan by degrees accosts us artfully by indirect means, until he holds us ensnared in his delusions. Then indeed being blinded, we break forth into open rebellion. [1] We must then meet this danger in due time, and it is one that is nigh us all, for nothing is more possible than to be deceived; and from this deception comes at length hardness of heart. We hence see how necessary it is for us to be roused by the incessant goads of exhortations. Nor does the Apostle give only a general precept, that all should take heed to themselves, but he should have them also to be solicitous for the salvation of every member, so that they should not suffer any of those who had been once called to perish through their neglect, and he who feels it his duty so to watch over the salvation of the whole flock as to neglect no one sheep, performs in this case the office of a good shepherd. While it is called today. He now applies what David said more particularly to his own subjects; for he reminds us that the word today, mentioned in the Psalm, ought not to be confined to the age of David, but that it comprehends every time in which God may address us. As often, then, and as long as he opened his sacred mouth to teach us, let this sentence come to our minds, "Today, if ye will hear his voice". In the same way Paul teaches us that when the Gospel is preached to us, it is the accepted time in which God hears us, and the Day of salvation in which he helps us. (2-Corinthians 6:2.) Now, of this opportunity we ought to avail ourselves; for if through our sloth we suffer it to pass by, we shall hereafter in vain deplore its loss. So Christ says, "Walk while ye have the light; come shortly shall the night." (John 12:35.) The particle while, then, or as long as, intimates that, The seasonable time will not continue always, if we be too slothful to follow when the Lord calls us. God knocks at our door; unless we open to him he will no doubt in his turn close against us the gate of his kingdom. In a word, too late will be their groans who despise the grace offered to them today. As, then, we know not whether God will extend his calling to tomorrow, let us not delay. Today he calls us; let us immediately respond to him, for there is no faith except where there is such a readiness to obey.

Footnotes

1 - "Deceitfulness of sin" is rendered by Stuart "sinful delusion." It ought rather to be "deceitful (or seductive) sin" as "deceitfulness of riches" in Matthew 13:22, means "deceitful riches." The "sin" was evidently that of apostasy: and it was deceitful, because there was a present prospect of relief from troubles and persecutions. The power of any sin to deceive and seduce, consists in some present gratification or interest. [16]See note on verse 6. -- Ed.

But exhort one another daily - This is addressed to the members of the churches; and it follows, therefore:
(1) that it is their duty to exhort their brethren; and,
(2) that it is their duty to do it "daily;" that is, constantly; see Hebrews 10:25; 1-Thessalonians 4:18; 1-Thessalonians 5:11; note, Romans 12:8. While this is the special duty of the ministers of the gospel 1-Timothy 6:2; 2-Timothy 4:2; Titus 2:6, Titus 2:15, it is also the duty of all the members of the churches, and a most important, but much-neglected duty. This does not refer to "public" exhortation, which more appropriately pertains to the ministers of the gospel, but to that private watch and care which the individual members of the church should have over one another. But in what eases is such exhortation proper? What rules should regulate it? I answer, it may be regarded as a duty, or is to be performed in such cases as the following:
(1) Intimate friends in the church should exhort and counsel one another; should admonish each other of their faults; and should aid one another in the divine life.
(2) parents should do the same thing to their children. They are placed particularly under their watch and care. A pastor cannot often see the members of his flock in private; and a parent may greatly aid him in his work by watching over the members of their families who are connected with the church.
(3) Sunday School teachers may aid much in this duty. They are to be assistants to parents and to pastors. They often have under their care youthful members of the churches. They have an opportunity of knowing their state of mind, their temptations, and their dangers better than the pastor can have. It should be theirs, therefore, to exhort them to a holy life.
(4) the aged should exhort the young. Every aged Christian may thus do much for the promotion of religion. His experience is the property of the church; and he is bound so to employ it as to be useful in aiding the feeble, reclaiming the wandering, recovering the backslider, and directing the inquiring. There is a vast amount of "spiritual capital" of this kind in the church that is unemployed, and that might be made eminently useful in helping others to heaven.
(5) church members should exhort one another. There may not be the intimacy of personal friendship among all the members of a large church, but still the connection between them should be regarded as sufficiently tender and confidential to make it proper for anyone to admonish a brother who goes astray. They belong to the same communion. They sit down at the same supper of the Lord. They express their assent to the same articles of faith. They are regarded by the community as united. Each member sustains a portion of the honor and the responsibility of the whole; and each member should feel that he has a right, and that it is his duty to admonish a brother if he goes astray. Yet this duty is greatly neglected. In what church is it performed? How often do church members see a fellow member go astray without any exhortation or admonition! How often do they hear reports of the inconsistent lives of other members and perhaps contribute to the circulation of those reports themselves, without any pains taken to inquire whether they are true! How often do the poor fear the rich members of the church, or the rich despise the poor, and see one another live in sin, without any attempt to entreat or save them! I would not have the courtesies of life violated. I would not have any assume a dogmatical or dictatorial air. I would have no one step out of his proper sphere of life. But the principle which I would lay down is, that the fact of church membership should inspire such confidence as to make it proper for one member to exhort another whom he sees going astray. Belonging to the same family; having the same interest in religion; and all suffering when one suffers, why should they not be allowed tenderly and kindly to exhort one another to a holy life?
While it is called Today - While life lasts; or while you may be permitted to use the language "Today hear the voice of God." The idea is, that the exhortation is not to be intermitted. It is to be our daily business to admonish and exhort one another. Christians are liable every day to go astray; every day they need aid in the divine life; and they who are fellow-heirs with them of salvation should be ever ready to counsel and advise them.
Lest any of you be hardened - the notes at Hebrews 3:8. It is possible for Christians to become in a sense hardened. Their minds become less sensitive than they were to the claims of duty, and their consciences become less tender. Hence, the propriory of mutual exhortation, that they may always have the right feeling, and may always listen to the commands of God.
The deceitfulness of sin - See the notes at Ephesians 4:22. Sin is always deceitful. It promises more than it performs. It assures us of pleasure which it never imparts. It leads us on beyond what was supposed when we began to indulge in it. The man who commits sin is always under a delusion; and sin, if he indulges it, will lead him on from one step to another until the heart becomes entirely hardened. Sin puts on plausible appearances and preferences; it assumes the name of virtue; it offers excuses and palliations, until the victim is snared, and then spell-bound he is hurried on to every excess. If sin was always seen in its true aspect when man is tempted to commit it, it would be so hateful that he would flee from it with the utmost abhorrence. What young man would become a drunkard if he saw when he began exactly the career which he would run? What young man, now vigorous and healthful, and with fair prospects of usefulness and happiness would ever touch the intoxicating bowl, if he saw what he "would be" when he became a sot? What man would ever enter the room of the gambler if he saw just where indulgence would soon lead him, and if at the commencement he saw exactly the wo and despair which would inevitably ensue? Who would become a voluptuary and a sensualist, if he saw exactly the close of such a career? Sin deceives, deludes, blinds. Men do not, or will not, see the fearful results of indulgence. They are deluded by the hope of happiness or of gain; they are drawn along by the fascinations and allurements of pleasure until the heart becomes hard and the conscience seared - and then they give way without remorse. From such a course, the apostle would have Christians guarded by kind and affectionate exhortation. Each one should feel that he has an interest in keeping his brother from Such a doom; and each Christian thus in danger should be willing to listen to the kind exhortation of a Christian brother.

But exhort one another daily - This supposes a state of chose Church fellowship, without which they could not have had access to each other.
While it is called to-day - Use time while you have: it, for by and by there will be no more present time; all will be future; all will be eternity. Daily signifies time continued. To-day, all present time. Your fathers said: Let us make ourselves a captain, and return back unto Egypt, Numbers 14:4. Thus they exhorted each other to depart from the living God. Be ye warned by their example; let not that unbelieving heart be in you that was in them; exhort each other daily to cleave to the living God; lest, if ye, do not, ye, like them, may be hardened through the deceitfulness of sin.

But exhort one another daily, (i) while it is called To day; lest any of you be hardened through the deceitfulness of sin.
(i) While today lasts, that is to say, so long as the gospel is offered to us.

But exhort one another daily,.... In order to prevent unbelief and apostasy. The phrase is sometimes rendered, "comfort one another", or, "yourselves together", as in 1-Thessalonians 5:11 which the saints may do, by discoursing together about divine things; by praying together; by instructing one another in the doctrines of the Gospel; by putting one another in mind of the covenant of grace, and its promises; and by observing the near approach of everlasting happiness with Christ. And though the business of exhortation greatly belongs to ministers of the word, yet it ought not to be neglected by private believers; who ought, when it becomes necessary, to exhort one another to prayer; to an attendance on the word and ordinances; to a regard to their conversations; to a close adherence to their profession; and to a believing view and consideration of Christ, the apostle and high priest of it; and to a due concern for his truth and interest: and this should be done in love, with good and consolatory words, and in things, in which the saints are concerned, and do themselves regard; and it is an affair which requires prudence and faithfulness; and supposes that God's own people may be dull, heavy, and sluggish; and this is to be done "daily", every day, as often as there is an occasion, and an opportunity for it; and
while it is called today; while the Gospel dispensation continues; or while the time of life lasts. This shows that the phrase "today", in Psalm 95:7 did not respect David's time only. The Syriac version renders it, "until that day which is called today": until the everlasting day appears, when there will be no need of such exhortations, nor any danger of what follows:
lest any of you be hardened through the deceitfulness of sin; actual sin, which is a transgression of the law; every sin is of an hardening nature, and by being often committed, an habit is contracted, and a callousness brought upon the heart and conscience; or the corruption of nature, indwelling sin, may be meant; an evil and a corrupt heart, which deceives through promises of pleasure, or profit to a man's self, or of secrecy and impunity; it suggests the power a man has to repent at pleasure, and the mercy of God, by which means the man is drawn in to it, and by frequent repeating it, grows hardened in it.

one another--Greek, "yourselves"; let each exhort himself and his neighbor.
daily--Greek, "on each day," or "day by day."
while it is called To-day--while the "to-day" lasts (the day of grace, Luke 4:21, before the coming of the day of glory and judgment at Christ's coming, Hebrews 10:25, Hebrews 10:37). To-morrow is the day when idle men work, and fools repent. To-morrow is Satan's to-day; he cares not what good resolutions you form, if only you fix them for to-morrow.
lest . . . of you--The "you" is emphatic, as distinguished from "your fathers" (Hebrews 3:9). "That from among you no one (so the Greek order is in some of the oldest manuscripts) be hardened" (Hebrews 3:8).
deceitfulness--causing you to "err in your heart."
sin--unbelief.

But, to prevent it, exhort one another, while it is called To - day - This to - day will not last for ever. The day of life will end soon, and perhaps the day of grace yet sooner.
