Psalm 127:1-3 ESV
Unless the LORD builds the house,
those who build it labor in vain.
Unless the LORD watches over the city,
the watchman stays awake in vain.
It is in vain that you rise up early
and go late to rest,
eating the bread of anxious toil;
for he gives to his beloved sleep.
Behold, children are a heritage from the LORD,
the fruit of the womb a reward.
