One work - The healing of the man on the Sabbath, John 5.

Ye all marvel - You all wonder or are amazed, and particularly that it was done on the Sabbath. This was the particular ground of astonishment, that he should dare to do what they esteemed a violation of the Sabbath.

I have done one work - That of curing the impotent man, already referred to. See John 5:9.

And ye all marvel - or, ye all marvel because of this. Some have δια τουτο, in connection with θαυμαζετε, which the common pointing makes the beginning of the next verse, and which, in our common version, is translated therefore; but this word conveys no meaning at all, in the connection in which it is thus placed. Proof of this construction Kypke gives from Themistius, Strabo, and Aelian. All the eminent critics are on the side of this arrangement of the words.

Jesus answered and said unto them,.... Taking no notice of their passion, reproach, and blasphemy; but proceeding upon the thing he had in view, and which he was determined to reassume, and vindicate himself in;

I have done one work; that is, on the sabbath day; meaning, his cure of the man that had had a disorder eight and thirty years, who lay at Bethesda's pool; which single action, they charged with being a breach of the sabbath, he mentions with a view to their many, and daily violations of it:

and ye all marvel; at it, as a thing unheard of, as a most shocking piece of iniquity, as an intolerable evil; wondering that any man should have the front, to bid another take up his bed and walk, on the sabbath day: they did not marvel at the miracle that was wrought; but were amazed, offended, and disturbed, at its being done on the sabbath day.

One work (ἓν ἔργον)

The healing on the Sabbath (John 5:1-8).

{8} Jesus answered and said unto them, I have done one work, and ye all marvel.

(8) The sabbath day (which is here set before us as a standard of all ceremonies) was not appointed to hinder, but to further and practise God's works, amongst which the main one is the love of our neighbour.

7:21 I have done one work. He goes back to the cause of the enmity of the rulers, the healing of the impotent man at the pool of Bethesda on the Sabbath day, about eighteen months before. See Joh 5:16.

7:21 I did - At the pool of Bethesda: one work - Out of many: and ye all marvelled at it - Are amazed, because I did it on the Sabbath day.

21-24. I have done one work, &c.-Taking no notice of the popular appeal, as there were those there who knew well enough what He meant, He recalls His cure of the impotent man, and the murderous rage it had kindled (Joh 5:9, 16, 18). It may seem strange that He should refer to an event a year and a half old, as if but newly done. But their present attempt "to kill Him" brought up the past scene vividly, not only to Him, but without doubt to them, too, if indeed they had ever forgotten it; and by this fearless reference to it, exposing their hypocrisy and dark designs, He gave His position great moral strength.

7:14-24 Every faithful minister may humbly adopt Christ's words. His doctrine is not his own finding out, but is from God's word, through the teaching of his Spirit. And amidst the disputes which disturb the world, if any man, of any nation, seeks to do the will of God, he shall know whether the doctrine is of God, or whether men speak of themselves. Only those who hate the truth shall be given up to errors which will be fatal. Surely it was as agreeable to the design of the sabbath to restore health to the afflicted, as to administer an outward rite. Jesus told them to decide on his conduct according to the spiritual import of the Divine law. We must not judge concerning any by their outward appearance, but by their worth, and by the gifts and graces of God's Spirit in them.
