1 Corinthians 11:29 in the King James Version
For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body.
Context
28 But let a man examine himself, and so let him eat of the bread and drink of the cup.
29 For he who eats and drinks in an unworthy way eats and drinks judgment to himself if he doesn’t discern the Lord’s body.
30 For this cause many among you are weak and sickly, and not a few sleep.
