John Wesley on Zechariah 10:4

Out of him - From God. The corner - The prince or ruler, who is in a polity as a corner - stone in buildings. The nail - Which fastens the tents of war, or the timber together in a house. The battle bow - All warlike provision. Every oppressor - Or collector of tribute. It was from God that Nebuchadnezzar mightily prevailed, and opprest Israel; and it is from God also, that Judah grows up to such power, as to be able to cope with his adversaries, and to impose tribute on them.
