the war-bow used in fighting (Zec 9:10; 10:4). "Thy bow was made quite naked" (Hab 3:9) means that it was made ready for use. By David's order (2Sa 1:18) the young men were taught the use, or rather the song of the bow. (See Armour, Bow.)
and he ordered that the Judahites be taught [The Song of] the Bow. It is written in the Book of Jashar:
You took the sheath from Your bow; the arrows are ready to be used with an oath. Selah You split the earth with rivers.
I will cut off the chariot from Ephraim and the horse from Jerusalem. The bow of war will be removed, and He will proclaim peace to the nations. His dominion will extend from sea to sea, from the Euphrates River to the ends of the earth.
From them will come the cornerstone, from them the tent peg, from them the battle bow, from them every ruler. Together
