(KJV)
Except the LORD build the house,
It is vain for you to rise up early,
to sit up late, to eat the bread of sorrows:
for so he giveth his beloved sleep.
Lo, children are an heritage of the LORD:
and the fruit of the womb is his reward.
As arrows are in the hand of a mighty man;
so are children of the youth.
Happy is the man that hath his quiver full of them:
they shall not be ashamed,
but they shall speak with the enemies in the gate.
