Offer the sacrifices of righteousness,.... Offer for sacrifice things righteously gotten, for the Lord hates robbery for burnt offering, Isa 61:8. Some respect may be had to the unrighteous acquisitions of Absalom and his men, and who were now in possession of Jerusalem, and of the altars of the Lord, and were sacrificing on them; in which they gloried; and to which this may be opposed.
Likewise sacrifices of righteousness are such as were according to the law, and were offered in a right manner; which were not maimed, nor had any blemish in them; see Mal 1:13; and particularly such as were offered up in the faith of the great sacrifice, Christ; for, without faith, it is impossible to please God by any sacrifice.
And this sense is confirmed by the following clause, which requires trust in the Lord. Moreover, righteousness, with the Jews, signifies alms, beneficence, showing mercy to the indigent; and acts of liberality are sacrifices, with which God is well pleased; and which are preferred by him to the sacrifices of the ceremonial law, Heb 13:16.
The sacrifices also of a broken heart, and of a contrite spirit, are such as God esteems of; he looks to those that have them, and dwells with them. And to this sense the Chaldee paraphrase inclines, in which the words are thus paraphrased;"subdue your corruptions, and it shall be reckoned to you as a sacrifice of righteousness?'
'and why may not the sacrifice of praise for mercies received, especially for the righteousness of Christ, be at least included, if not principally designed; since these are sacrifices which, under the ceremonial law, were more pleasing to God than others; and are always acceptable to him through Jesus Christ our Lord?
Agreeably to this, Aben Ezra thinks the peace offerings are intended, which were in a way of thanksgiving; and are opposed to sin offerings, and trespass offerings, and burnt offerings; from the last of which sacrifices of righteousness are distinguished in Ps 51:19;and put your trust in the Lord: not in your strength, in horses and chariots, and numbers of men; nor in wise counsels, nor in riches, nor in fleshly privileges, nor in works of righteousness, or sacrifices of righteousness: for though they are to be performed, they are not to be trusted in; nor in your own hearts.
And while the psalmist is striking at the false confidence of the sons of men he is addressing, he may at the same time be thought to be encouraging those that were with him to trust in the Lord, Jehovah, the Son of God, before spoken of by him as the object of trust, Ps 2:12; to trust in his person for the acceptance of their persons and sacrifices of righteousness; and in his righteousness for justification; in his blood for pardon; in his sacrifice for expiation of sin; in his fulness for daily supplies; and in his power for protection and safety.
And it is right to trust in him at all times; in times of affliction, temptation, and desertion: he is always the same; in him is everlasting strength; he has an heart as well as an ability to help and succour, and none ever trusted in him and were confounded.
