'Arrow' in the Bible

I will bend Judah as my bow; I will load the bow with Ephraim, my arrow! I will stir up your sons, Zion, against yours, Greece, and I will make you, Zion, like a warrior's sword.

And the LORD shall be seen over them, and his arrow shall go forth as the lightning: and the Lord GOD shall blow the trumpet, and shall go with whirlwinds of the south.
