'Eating' in the Bible

Concerning the eating then of the things sacrificed to idols, we have known that an idol is nothing in the world, and that there is no other God except one;

See Israel according to the flesh! are not those eating the sacrifices in the fellowship of the altar?

for each his own supper doth take before in the eating, and one is hungry, and another is drunk;

for he who is eating and drinking unworthily, judgment to himself he doth eat and drink -- not discerning the body of the Lord.
