Psalms 127:4

²It is vain for you to rise up early, to stay up late, eating the bread of toil; for he gives sleep to his loved ones.

³Behold, children are a heritage of Yahweh. The fruit of the womb is his reward.

⁴As arrows in the hand of a mighty man, so are the children of youth.

⁵Happy is the man who has his quiver full of them. They won’t be disappointed when they speak with their enemies in the gate.
