In Psalm 127 we hear that “arrows in the hand of a warrior are the children of one’s youth.” Rich Lusk exaplains:
Psalm 127 talks about the quiver full of arrows; the man’s children are his quiver full of arrows. It doesn’t do any good to sharpen and straighten those arrows if you are just going to leave them in the quiver. They have to get out of the quiver. They have to be shot, they have to be fired, and they have to be aimed into the heart of the enemy.
