Wist not - Knew not.

Had conveyed himself away - Was lost in the crowd. He had silently mingled with the multitude, or had passed on with the crowd unobserved, and the man had been so rejoiced at his cure that he had not even asked for the name of his benefactor.

Jesus had conveyed himself away - Or, had withdrawn himself. And this he might easily do, as there was a crowd in the place. Some think the words indicate, that Jesus withdrew on seeing a multitude in the place, i.e. raising a tumult, because of the man's carrying his bed (margin: Or, from the multitude that was). He had not yet finished his work, and would not expose himself to the envy and malice of the Jewish rulers.

And he that was healed, wist not who he was,.... He had never seen, and perhaps had never heard of Christ before, and so knew him not; and besides, Christ gave him no opportunity of conversing with him, or so much as to ask him who he was:

for Jesus had conveyed himself away; had slipped away, as soon as ever he had wrought the miracle:

a multitude being in that place; or "from the multitude that were in that place"; not that he hid himself among them, and there remained undiscovered; but he passed through them, and went his way to the temple, where he found the man he had healed, as in the following verse.

He that was healed (ἰαθεὶς)

Compare John 5:10, and note the different word for healing. See references there.

Who it was (τίς ἐστιν)

The present tense, who it is.

Had conveyed Himself away (ἐξένευσεν)

The verb means, literally, to turn the head aside, in order to avoid something. Hence, generally, to retire or withdraw. Only here in the New Testament.

And he that was healed wist not who it was: for Jesus had conveyed himself away, a multitude being in that place.

a multitude...: or, from the multitude that was

13. he that was healed wist not, &c.-That some one, with unparalleled generosity, tenderness and power, had done it, the man knew well enough: but as he had never heard of Him before, so he disappeared too quickly for any inquiries.

conveyed himself away-slipped out of the crowd that had gathered, to avoid both hasty popularity and precipitate hatred (Mt 12:14-19).

5:10-16 Those eased of the punishment of sin, are in danger of returning to sin, when the terror and restraint are over, unless Divine grace dries up the fountain. The misery believers are made whole from, warns us to sin no more, having felt the smart of sin. This is the voice of every providence, Go, and sin no more. Christ saw it necessary to give this caution; for it is common for people, when sick, to promise much; when newly recovered, to perform only something; but after awhile to forget all. Christ spoke of the wrath to come, which is beyond compare worse than the many hours, nay, weeks and years of pain, some wicked men have to suffer in consequence of their unlawful indulgences. And if such afflictions are severe, how dreadful will be the everlasting punishment of the wicked!
