Look at the Bible in Jeremiah:-
7:21 Thus saith the LORD of hosts, the God of Israel; Put your burnt offerings unto your sacrifices, and eat flesh.
7:22 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:
7:23 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.
7:24 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.
God dd not ordain the sacrifices, the Rabbis made them up or copied them from pagan religions.
Obey God, follow His way, again contradicting the supposed sacrifice of Jesus.
They did not follow this God given way and destroyed themselves.
Sounds all too familiar!
