John 5:6

Jesus when He saw the man lying and had ascertained (γνοὺς, having learned from the man or his friends) that already he had passed a long time (in that infirmity) says: θέλεις ὑγιὴς γενέσθαι; “Do you wish to become whole (healthy)?” This question was put to attract the man's attention and awaken hope. But the man is hopeless: it is not a question of will, he says, but of opportunity. His very weakness enabled others to anticipate him; ἐν ᾧ ἔρχομαι ἐγὼ, “while I am coming,” he could, then, move a little, but not quickly enough. At each bubbling up of the water, apparently only one could be healed. The ἄλλος πρὸ ἐμοῦ καταβαίνει was a great aggravation of his case.
