Matthew Poole and continuators on Jeremiah 7:22

22 For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt-offerings or sacrifices.

Some would argue from hence, that sacrifices were at first an invention of men, as Papists, and Socinians, and because they should not be used to Idols, God gave way for the introducing them into his Worship; but it is evident in Scripture that they have been of Divine institution ever since Adam, Gen. 4.3, 4. as to the meaning of the words. God doth not condemn them, or deny them, save only comparatively in respect of obedience, not so much these, as obeying his Commands, 1 Sam. 15.22. Hos. 6.6. i. e. Mercy rather than Sacrifice. Negatives are often put for comparatives, Gen. 45.8. Exod. 16.8. Joh. 5.45. Hence the Heb. is the matter of burnt offerings, for sacrifices were not instituted for themselves, but for other uses, and to be signs of Faith in his promises, and obedience to his Commands, as in the next verse, where the condition, promise and end are all set down.
