1 Corinthians 11:28-34King James Version (KJV)
28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
30 For this cause many are weak and sickly among you, and many sleep.
31 For if we would judge ourselves, we should not be judged.
32 But when we are judged, we are chastened of the Lord, that we should not be condemned with the world.
33 Wherefore, my brethren, when ye come together to eat, tarry one for another.
34 And if any man hunger, let him eat at home; that ye come not together unto condemnation. And the rest will I set in order when I come.
