zechariah 13:6 And one shall say unto him, What are these wounds in thine hands? Then he shall answer, Those with which I was wounded in the house of my friends. - Free Bible Online

      6. wounds in thine hand--The interrogator still suspects him: "If so, if you have never pretended to be a prophet, whence come those wounds?" The Hebrew is literally, "between thine hands." The hands were naturally held up to ward off the blows, and so were "thrust through" (Zec 13:3) "between" the bones of the hand. Stoning was the usual punishment; "thrusting through" was also a fit retribution on one who tried to "thrust Israel away" from the Lord (De 13:10); and perfects the type of Messiah, condemned as a false prophet, and pierced with "wounds between His hands." Thus the transition to the direct prophecy of Him (Zec 13:7) is natural, which it would not be if He were not indirectly and in type alluded to.
      wounded in . . . house of my friends--an implied admission that he had pretended to prophecy, and that his friends had wounded him for it in zeal for God (Zec 13:3). The Holy Spirit in Zechariah alludes indirectly to Messiah, the Antitype, wounded by those whom He came to befriend, who ought to have been His "friends," who were His kinsmen (compare Zec 13:3, as to the false prophet's friends, with Mr 3:21, "His friends," Margin, "kinsmen"; Joh 7:5; "His own," Joh 1:11; the Jews, "of whom as concerning the flesh He came," Ro 9:5), but who wounded Him by the agency of the Romans (Zec 12:10).
