1 Corinthians 11:21

For in eating
Not at the Lord's table, but at tables spread for them in the place of divine worship, where everyone brought his own food, under a pretence that others, particularly the poor, should eat with him; but instead of that, he sat down and ate it himself, and would not stay till the rest came, to eat together:

but everyone taketh before other his own supper;
that is, without tarrying till all came together, in order to eat a friendly meal with each other, to encourage and increase brotherly love, one would sit down and fill himself before another came; so that some went without, whilst others had too much; and thus the designed end was not answered, and the whole was a piece of confusion and disorder:

and one is hungry, and another drunken;
he that came late had nothing to eat, and so was hungry; when he that was first either eat and drank to excess, or at least very plentifully, so that he was very cheerful, and more disposed to carnal mirth, than in a serious and solemn manner to partake of the Lord's supper; and who is thought to be the rich man, who brought his own provisions, and ate them himself when he had done; as the poor may be meant by the hungry, who having no food to bring with them, and none being communicated to them by the rich, were in want, and starving; so that here were many abuses justly chargeable on them. Dr. Lightfoot is of opinion, that by him that was "drunken" meant the Jew that ate the paschal supper, of which he ate and drank freely; and by him that was "hungry", the Gentile, who was so not out of poverty and necessity, but because he refused and avoided eating of the ante-supper, as savouring of Judaism; and so here was a schism and division among them.
