By him, therefore, let us offer the sacrifice of praise to God, etc. He returns to that particular doctrine to which he had referred, respecting the abrogation of the ancient ceremonies; and he anticipates an objection that might have been made; for as the sacrifices were attached as appendages to the tabernacle, when this was abolished, it follows that the sacrifices also must have ceased. But the Apostle had taught us that as Christ had suffered without the gate, we are also called thither, and that hence the tabernacle must be forsaken by those who would follow him. Here a question arises, whether any sacrifices remained for Christians; for this would have been inconsistent, as they had been instituted for the purpose of celebrating God' worship. The Apostle, therefore, in due time meets this objection, and says that another kind of sacrifice remains for us, which no less pleases God, even the offering of the calves of our lips, as the Prophet Hoses says. [1] (Hosea 14:2.) Now that the sacrifice of praise is not only equally pleasing to God, but of more account than all those external sacrifices under the Law, appears evident from the fiftieth Psalm; for God there repudiates all these as things of nought, and bids the sacrifice of praise to be offered to him. We hence see that it is the highest worship of God, justly preferred to all other exercises, when we acknowledge God's goodness by thanksgiving; yea, this is the ceremony of sacrificing which God commends to us now. There is yet no doubt but that under this one part is included the whole of prayer; for we cannot give him thanks except when we are heard by him; and no one obtains anything except he who prays. He in a word means that without brute animals we have what is required to be offered to God, and that he is thus rightly and really worshipped by us. But as it was the Apostle's design to teach us what is the legitimate way of worshipping God under the New Testament, so by the way he reminds us that God cannot be really invoked by us and his name glorified, except through Christ the mediator; for it is he alone who sanctifies our lips, which otherwise are unclean, to sing the praises of God; and it is he who opens a way for our prayers, who in short performs the office of a priest, presenting himself before God in our name.

Footnotes

1 - The words in Hosea are not regimen, but in apposition. "So will we render calves, our lips." Such is the meaning given by the Targum, though the Vulg. puts the words in construction, "the calves of our lips." Instead of the calves offered in sacrifices, the promise made was to offer their lips, that is, words which they were required to take, "Take with you words". The Sept., Syr., and Arab. Render the phrase as here given, "the fruit of our lips," only the Apostle leaves out "our". There is the same meaning, though not exactly the same words. -- Ed.

By him, therefore - The Jews approached God by the blood of the sacrifice and by the ministry of their high priest. The exhortation of the apostle here is founded on the general course of argument in the Epistle "In view of all the considerations presented respecting the Christian High Priest - his dignity, purity, and love; his sacrifice and his intercession, let us persevere in offering through him praise to God." That is, let us persevere in adherence to our religion.
The sacrifice of praise - For all the mercies of redemption. The Jews, says Rosenmuller (Alte u. neue Morgenland, in loc.), had a species of offerings which they called "peace-offerings, or friendship-offerings." They were designed not to produce peace or friendship with God, but to preserve it. Burnt-offerings, sin-offerings, and trespass-offerings, were all on account of transgression, and were designed to remove transgression. But in their peace-offerings, the offerer was regarded as one who stood in the relation of a friend with God, and the oblation was a sign of thankful acknowledgment for favors received. or they were connected with vows in order that further blessings might be obtained, or they were brought voluntarily as a means to continue themselves in the friendship and favor of God; Leviticus 7:11-12; compare Jenning's Jew. Ant. i. 335.
That is, the fruit of our lips - The phrase "fruit of the lips." is a Hebraism, meaning what the lips produce; that is, words; compare Proverbs 18:20; Hosea 14:2.
Giving thanks to his name - To God; the name of one being often put for the person himself. "Praise" now is one of the great duties of the redeemed. It will be their employment forever.

By him therefore let us offer the sacrifice of praise - He has now fulfilled all vision and prophecy, has offered the last bloody sacrifice which God will ever accept; and as he is the gift of God's love to the world, let us through him offer the sacrifice of praise to God continually, this being the substitute for all the Levitical sacrifices.
The Jews allowed that, in the time of the Messiah, all sacrifices, except the sacrifice of praise, should cease. To this maxim the apostle appears to allude; and, understood in this way, his words are much more forcible. In Vayikra Rabba, sect. 9, fol. 153, and Rabbi Tanchum, fol. 55: "Rabbi Phineas, Rabbi Levi, and Rabbi Jochanan, from the authority of Rabbi Menachem of Galilee, said, In the time of the Messiah all sacrifice shall cease, except the sacrifice of praise." This was, in effect, quoting the authority of one of their own maxims, that now was the time of the Messiah; that Jesus was that Messiah; that the Jewish sacrificial system was now abolished; and that no sacrifice would now be accepted of God, except the sacrifice of praise for the gift of his Son.
That is, the fruit of our lips - This expression is probably borrowed from Hosea 14:2, in the version of the Septuagint, καρπον χειλεων which in the Hebrew text is פרים שפתינו parim sephatheinu, "the heifers of our lips." This may refer primarily to the sacrifices, heifers, calves, etc., which they had vowed to God; so that the calves of their lips were the sacrifices which they had promised. But how could the Septuagint translate פרים parim, calves, by καρπον, fruit? Very easily, if they had in their copy פרי peri, the mem being omitted; and thus the word would be literally fruit, and not calves. This reading, however, is not found in any of the MSS. hitherto collated.

(9) By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of [our] lips giving thanks to his name.
(9) Now that those physical sacrifices are taken away, he teaches us that the true sacrifices of confession remain, which consist partly in giving thanks, and partly in liberality, with which sacrifices indeed God is now delighted.

By him therefore let us offer the sacrifice of praise,.... For temporal and spiritual mercies; particularly for sanctification, or expiation of sin, by the blood of Christ; and for heaven, the continuing city, that is to come: this sacrifice is not a proper, nor a propitiatory one, but spiritual and evangelical; it is enjoined by God, is well pleasing to him, and glorifies him; and is our reasonable service, that believe in Christ; for being made priests by him to God, and having faith in him, such are capable of offering it aright; to do which, they are under the greatest obligations: and it is to be offered up by Christ, who is the same yesterday, today, and for ever; and who has suffered without the gate, that he might sanctify the people by his blood; it is to be done in imitation of him, and by his assistance; and for him, and blessings in him; and on him, as the altar, which sanctifies the gift; and through him, as the high priest and Mediator; for, as there is no coming to God but by Christ, and all our mercies come to us through him, and our thanksgivings are only acceptable to God on his account, it must be right to offer them up by him: and that,
to God continually: as the Creator and Preserver of us, in our beings; as the Father of mercies; as the Father of Christ; and as our covenant God and Father in him; since he is always bestowing mercies on us, of one kind or another; and, therefore, should be continually praised, even in times of adversity, affliction, and temptation; in the midst of reproach and persecution; even when unsettled in mind, body, and estate; since there is a continuing city to come; nor can a believer be in any state of life but he has something to be thankful for:
that is, the fruit of our lips; the sacrifice of praise is so called, in allusion to the offering of the firstfruits under the law; and to distinguish it from legal sacrifices; and to show in what way and manner we are to praise God, namely, with our lips: in Hosea 14:2 which is thought to be referred to here, it is, "the calves of our lips"; sacrifices of praise being instead of calves: and the apostle interprets it in great agreement with the Jewish writers; the Chaldee paraphrase explains it by , "the words of their lips": and so Jarchi, , "the words of our lips"; and Kimchi, , "the confession of our lips": and it may be observed, that there is a great nearness in "calves", and "fruit"; though perhaps rather the phrase is borrowed from Isaiah 57:19 where it is expressly had; the Septuagint indeed have it in Hosea 14:2 & the apostle adds, for further explanation,
giving thanks to his name; to the name of God; to the glory of his name; to the honour of his divine perfections; for mercies of every kind: the word signifies "a speaking together"; and may design not only the conjunction of the heart and tongue together in praise, but a social giving thanks to God by the saints, as a body together: the phrase , "the sacrifice of praise", is used by the Septuagint in 2-Chronicles 29:31. The apostle having shown that legal sacrifices were all superseded and abolished by the sacrifice of Christ, which is the design of this epistle, points out what sacrifice believers should offer up to God, under the Gospel dispensation; and the Jews themselves say, that
"in future time (i.e. in the days of the Messiah) all sacrifices shall cease, but , "the sacrifice of praise" shall not cease (b).''
(b) Vajikra Rabba, sect. 9. fol. 153. 1. & sect 27. fol. 168. 4.

As the "altar" was mentioned in Hebrews 13:10, so the "sacrifices" here (compare 1-Peter 2:5, namely, praise and doing good, Hebrews 13:16). Compare Psalm 119:108; Romans 12:1.
By him--as the Mediator of our prayers and praises (John 14:13-14); not by Jewish observances (Psalm 50:14, Psalm 50:23; Psalm 69:30-31; Psalm 107:22; Psalm 116:17). It was an old saying of the rabbis, "At a future time all sacrifices shall cease, but praises shall not cease."
of praise--for salvation.
continually--not merely at fixed seasons, as those on which the legal sacrifices were offered, but throughout all our lives.
fruit of our lips-- (Isaiah 57:19; Hosea 14:2).
giving thanks--Greek, "confessing." BENGEL remarks that the Hebrew, "todah," is beautifully emphatic. It literally means "acknowledgment" or "confession." In praising a creature, we may easily exceed the truth; but in praising God we have only to go on confessing what He really is to us. Hence it is impossible to exceed the truth, and here is genuine praise.

The sacrifice - The altar is mentioned, Hebrews 13:10; now the sacrifices: Praise; Beneficence; with both of which God is well pleased.
