This in the King James bible Jeremiah chapter 7 veres 21 -23 - God did NOT tell them to sacrifice animals 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:<quoted text>Sidestep questions much? Killing to survive is different than a god demanding you kill for pleasure. But the question is why would your god need man to kill animals for blood ritual sacrifice???
23 But this thing commanded I them, saying, Obey my voice, and I will be your God, and ye shall be my people: and walk ye in all the ways that I have commanded you, that it may be well unto you.
24 But they hearkened not, nor inclined their ear, but walked in the counsels and in the imagination of their evil heart, and went backward, and not forward.
