Psalm 127    

¹If Yahweh does not build a house, those who built it labored in vain. If Yahweh does not watch over a city, the watchman keeps awake in vain.
  ²It is in vain for you to rise up early, to lie down late, to eat the bread of strenuous labor; for he gives sleep to his beloved.
  ³Behold, children are an inheritance from Yahweh, the fruit of the womb is a reward.
  ⁴As arrows in the hand of a mighty man, so are the children of one’s youth.
  ⁵Blessed is the man who has his quiver full of them. They will not be put to shame when they speak with their enemies at the gate.
