Psalms 127:1-4 NIV
Unless the LORD builds the house,
the builders labor in vain.
Unless the LORD watches over the city,
the guards stand watch in vain.
In vain you rise early
and stay up late,
toiling for food to eat—
for he grants sleep to those he loves.
Children are a heritage from the LORD,
offspring a reward from him.
Like arrows in the hands of a warrior
are children born in one’s youth.
NIV: New International Version
