On the wall next to my desk is a small framed piece of calligraphy, a gift from a friend with a talented hand, with this passage from Psalm 127:
Lo, sons are a heritage from the LORD, the fruit of the womb a reward.
Like arrows in the hand of a warrior
are the sons of one's youth.
Happy is the man who has his quiver full of them!
He shall not be put to shame when he speaks with his enemies in the gate...
