1 Corinthians 11:28

But let a man examine himself, and so let him eat of that bread, and drink of that cup.

But let a man examine himself, and so let him eat of the bread, and drink of the cup.

But let a man prove himself, and so let him eat of the bread, and drink of the cup.

and let a man be proving himself, and so of the bread let him eat, and of the cup let him drink;

Each one must examine himself before he eats of the bread and drinks of the cup.
