Psalm 127:3-5 (New King James Version)

 ³ Behold, children are a heritage from the LORD,
         The fruit of the womb is a reward.
 ⁴ Like arrows in the hand of a warrior,
         So are the children of one’s youth.
 ⁵ Happy is the man who has his quiver full of them;
         They shall not be ashamed,
         But shall speak with their enemies in the gate.
