Psalms 51:19

19Then shalt thou accept sacrifices of righteousness In these words there is an apparent, but only an apparent, inconsistency with others which he had used in the preceding context. He had declared sacrifices to be of no value when considered in themselves, but now he acknowledges them to be acceptable to God when viewed as expressions or symbols of faith, penitence, and thanksgiving. He calls them distinctly sacrifices of righteousness, right, warrantable, and such as are offered in strict accordance with the commandment of God. The expression is the same employed in Psalms 4:5, where David uses it with a tacit condemnation of those who gloried in the mere outward form of ceremonies. We find him again exciting himself and others by his example to the exercise of gratitude, and to the expression of it openly in the solemn assembly. Besides sacrifices in general, two particular kinds of sacrifice are specified. Although some consider כליל, calil, and עולה, olah, to be both of one signification, others maintain with more correctness, that the first is to be understood as meaning the priest’s sacrifice, because in it the offering was consumed or burnt with fire. (274) In the enumeration which he makes, David designs to teach us that none of all the legal rites can find acceptance with God, unless they be used with a reference to the proper end of their institution. The whole of this verse has been figuratively applied by some to the kingdom of Christ, but the interpretation is unnatural and too refined. Thanksgivings are indeed called by Hosea “the calves of the lips,” (Hosea 14:2;) but it seems evident that in the passage before us there are conjoined along with the frame or disposition of the heart those solemn ceremonies which constituted part of the ancient worship.
