Children are an heritage of the LORD

Psalm 127:

A Song of degrees for Solomon.

Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain.

2 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.
