on Hebrews 13 :15
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.
on Hebrews 13 :15
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.

13:15 The sacrifice - The altar is mentioned, Heb 13:10; now the sacrifices: Praise; Beneficence; with both of which God is well pleased.
