Albert Barnes Commentary John 5:7

"The sick man answered him, Sir, I have no man, when the water is troubled, to put me into the pool: but while I am coming, another steppeth down before me." — John 5:7 (ASV)

Sir, I have no man, ... The answer of the man implied that he did wish it, but, in addition to all his other trials, he had no friend to aid him. This is an additional circumstance that heightened his affliction.
