He says he did not 'JUST' give them commands about burnt offerings.
Jeremiah 7:22 For when I brought your ancestors out of Egypt and spoke to them, I did not just give them commands about burnt offerings and sacrifices,
That is what happens when you let carnivores interpret the scripture for you. The same thing happens with the misguided punctuation and meat lovers interpretation of Genesis 9:2-5. The following is a real question but rather than actually going to the scripture to answer it most just assume the answer is "yes" because the slow brazen belly of a leopard is given dominion over the lusty mind of the carnal man:
"Did you offer unto Me slain beasts and sacrifices forty years in the wilderness, O house of Yisrael?" (Amos 5:25, Acts 7:42).
The answer is more likely, no, at least not literal physical animals.
The following is merely an example and not offered as "absolute" proof:
Numbers 11:4-6 KJV
4. And the mixt multitude that was among them fell a lusting: and the children of Israel also wept again, and said, Who shall give us flesh to eat?
5. We remember the fish, which we did eat in Egypt freely; the cucumbers, and the melons, and the leeks, and the onions, and the garlick:
6. But now our soul is dried away: there is nothing at all, beside this manna, before our eyes.
Look at the "flesh" they were desiring in the above passage: is there any actual "meat" from an animal except for the fish which is mentioned? Everything else is vegetables and herbs. The sacrificial commands are symbolic and prophetic: "The Torah and all the Prophets prophesied until Yochanan", (the Immerser) Matthew 11:13.
Psalm 51:10-19 KJV (Psalm of David)
10. Create in me a clean heart, O God; and renew a right spirit within me.
11. Cast me not away from thy presence; and take not thy holy spirit from me.
12. Restore unto me the joy of thy salvation; and uphold me with thy free spirit.
13. Then will I teach transgressors thy ways; and sinners shall be converted unto thee.
14. Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.
15. O Lord, open thou my lips; and my mouth shall shew forth thy praise.
16. For thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering.
17. The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.
18. Do good in thy good pleasure unto Zion: build thou the walls of Jerusalem.
19. Then shalt thou be pleased with the sacrifices of righteousness, with burnt offering and whole burnt offering: then shall they offer bullocks upon thine altar.
Two young bullocks: Torah and Prophets, (Moshe and Eliyahu).
One ram: Messiah Yeshua the Son of Elohim, (Genesis 22:13).
Seven lambs perfect unto you: Seven Spirits before the Throne.
Revelation 8:4
4. And the smoke of the incense of the prayers of the holy ones ascended up from the hand of the Angel before Elohim.
