'Sacrifices' in the Bible

But all believers do not recognize these facts. Some, from force of habit in relation to the idol, even now eat idol sacrifices as such, and their consciences, being but weak, are polluted.

Do not be worshipers of handmade gods, as some of them were; just as it is written [in Scripture], “The people sat down to eat and drink [after sacrificing to the golden calf at Horeb], and stood up to play [indulging in immoral activities].”

Behold Israel after the flesh: are not they which eat of the sacrifices partakers of the altar?
