'Sacrificial' in the Bible

Then the Lord said to me, “Go again, love a woman (Gomer) who is beloved by her husband and yet is an adulteress, even as the Lord loves the children of Israel, though they turn to other gods and love the raisin cakes [used in the feasts in pagan worship].”

As for My sacrificial offerings,They sacrifice the meat [as a mere formality] and eat it,But the Lord is not pleased with them and does not accept them.Now He will remember and take into account their wickedness and guilt,And punish them for their sins.They will return [in captivity] to [another] Egypt [that is, Assyria].
