Acts 18:6

Gentiles - A people; nations other than Israel.

Henceforth - From this time forth; from now on.

Raiment - Clothing; apparel; covering.

When they opposed - Αντιτασσομενων, Systematically opposing, putting themselves in warlike order against him: so the word implies.

And blasphemed - This is precisely the way in which they still act. They have no arguments against Jesus being the Messiah; but, having made a covenant with unbelief, as soon as they are pressed on this point, they rail and blaspheme. - See the Tela ignea Satanae, by Wagenseil.

He shook his raiment - This was an action similar to that of shaking the dust of the feet; see on Matthew 10:14 (note). See a parallel act, and its signification, in Nehemiah 5:13 : Also I Shook My Lap, and said, So shall God Shake every man From His House and From his Labor; even thus shall he be Shaken Out and Emptied. St. Paul's act on this occasion seems to have been the same with this of Nehemiah, and with the same signification; and it is likely that he was led by a Divine impulse to do it - thus signifying the shaking and emptying out of this disobedient people, which took place about sixteen years afterwards.

Your blood be upon your own heads - That is, ye alone are the cause of the destruction that is coming upon yourselves and upon your country.

I am clean - Καθαρος εγω, I am pure or innocent of your death and ruin. I have proposed to you the Gospel of Jesus Christ - the only means by which ye can be saved, and ye have utterly rejected it. I shall labor no more with you; and, from henceforth, shall confine my labors to the Gentiles. St. Paul must refer to the Jews and Gentiles of Corinth particularly; for he preached to the Jews occasionally in other places; see Acts 19:8, Acts 19:9; and several were brought to the knowledge of the truth. But it seems as if the Jews from this time systematically opposed the Gospel of Christ; and yet, general tenders of this salvation were made to them wherever the apostles came; and when they rejected them, the word was sent to the Gentiles; see Acts 19:8, Acts 19:9.

Pure from blood, or pure from guilt, is commonly expressed by καθαρος; thus Heliodorus, lib. i. p. 49: Εις δευρο διετελεσα καθαραν εμαυτην απο σης ὁμιλιας φυλαττουσα, Until now I have lived, preserving myself pure: and Alciphron, lib. i. epist. 7, ad. fin.: Ουδε μιαναι λυθρῳ τας χειρας, ἁς ἡ θαλαττα εκ παιδος εις δευρο καθαρας αδικηματων εφυλαξε, Nor to stain with pollution the hands which a seafaring life has kept from a child until now pure from iniquity.

And when they opposed themselves - To him and his message.

And blasphemed - See the notes on Acts 13:45.

He shook his raiment - As an expressive act of shaking off the guilt of their condemnation. Compare Acts 13:45. He shook his raiment to show that he was resolved henceforward to have nothing to do with them; perhaps, also, to express the fact that God would soon slake them off, or reject them (Doddridge).

Your blood ... - The guilt of your destruction is your own. You only are the cause of the destruction that is coming upon you. See the notes on Matthew 27:25.

I am clean - I am not to blame for your destruction. I have done my duty. The gospel had been fairly offered and deliberately rejected; and Paul was not to blame for their ruin, which he saw was coming upon them.

I will go ... - See Acts 13:46.

18:6 He shook his raiment - To signify he would from that time refrain from them: and to intimate, that God would soon shake them off as unworthy to be numbered among his people. I am pure - None can say this but he that has borne a full testimony against sin. From henceforth I will go to the Gentiles - But not to them altogether. He did not break off all intercourse with the Jews even at Corinth. Only he preached no more in their synagogue.
