“And when they opposed themselves, and blasphemed, he shook his raiment, and said unto them, Your blood be upon your own heads; I am clean: from henceforth I will go unto the Gentiles.”
King James Version (KJV)
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.
Ac 18:6 When they . . . blasphemed. Against Jesus Christ. The opposition became malignant. He shook [his] raiment. See PNT "Mt 10:14". Also see Ac 13:51. Your blood [be] upon your own heads. "I have done my duty. The responsibility is now yours".
