1 Corinthians 11:28-34

28But let a man prove himself, and so let him eat of the bread, and drink of the cup. 29For he that eateth and drinketh, eateth and drinketh judgment unto himself, if he discern not the body. 30For this cause many among you are weak and sickly, and not a few sleep. 31But if we discerned ourselves, we should not be judged. 32But when we are judged, we are chastened of the Lord, that we may not be condemned with the world. 33Wherefore, my brethren, when ye come together to eat, wait one for another. 34If any man is hungry, let him eat at home; that your coming together be not unto judgment. And the rest will I set in order whensoever I come.
