Charles Ellicott Commentary 1 Corinthians 11:28

"But let a man prove himself, and so let him eat of the bread, and drink of the cup." — 1 Corinthians 11:28 (ASV)

So let him eat.—This implies that a man should partake of this sacred feast only after he has carefully examined himself as to the spirit in which he was approaching such holy bread and wine.

On verses 28-32:

So many modifications are required in the Greek text of these verses (from which our translation is taken) to bring it into harmony with the best MSS., and so many changes are needed in the translation itself to convey the meaning of the original more clearly, that it is best to provide a consecutive translation of the whole passage here.

It should read as follows: But let a man prove himself and so let him eat of the bread and drink of the cup, for he that eats and drinks, eats and drinks judgment to himself if he does not discern the Body—(for this cause many among you are weak and sick, and some sleep)—but if we discerned ourselves, we should not be judged; but being judged, we are chastened by the Lord, so that we may not be finally condemned with the world.

There are several words in this sentence that require comment.
