Adam Clarke on Zechariah 10:4

Out of him came forth the corner - This is spoken of the tribe of Judah: all strength, counsel, and excellence came from that tribe. The corner stone, the ornament and completion of the building; the nail, by which the tents were fastened, and on which they hung their clothes, armor, etc., the battlebow, the choicest archers.

Every oppressor together - Those heroes and generals, by whom, under God, their foes should be totally routed. Newcome translates, "Every ruler together." Perhaps all this is spoken of the Messiah.
