Psalm 127; ASV
1 Except Jehovah build the house, they labor in vain that build it: except Jehovah keep the city, the watchman waketh but in vain.
2 It is vain for you to rise up early, to take rest late, to eat the bread of toil; (for) so he giveth unto his beloved sleep.
3 Lo, children are a heritage of Jehovah; (and) the fruit of the womb is (his) reward.
4 As arrows in the hand of a mighty man, so are the children of youth.
5 Happy is the man that hath his quiver full of them: they shall not be put to shame, when they speak with their enemies in the gate.
