Psalms 127:1-5 (NKJV)
Unless the Lord builds the house, they labor in vain who build it; unless the Lord guards the city, the watchman stays awake 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 gives His beloved sleep.
3 Behold, children are a heritage from the Lord, the fruit of the womb is a reward.
4 Like arrows in the hand of a warrior, so are the children of one’s youth. 5 Happy is the man who has his quiver full of them; they shall not be ashamed, but shall speak with their enemies in the gate.
