Psalm 127 is a Psalm of Solomon, the son and predecessor to King David. During David’s reign over Israel there was much war. During Solomon’s reign God gave Israel peace and the temple was built.
To summarize Psalm 127, it talks about God’s blessings on our homes and community.
Unless the Lord builds a house,
the work of the builders is wasted.
Unless the Lord protects a city,
guarding it with sentries will do no good.
2 It is useless for you to work so hard
from early morning until late at night,
anxiously working for food to eat;
for God gives rest to his loved ones.
3 Children are a gift from the Lord;
they are a reward from him.
4 Children born to a young man
are like arrows in a warrior’s hands.
5 How joyful is the man whose quiver is full of them!
He will not be put to shame when he confronts his accusers at the city gates.
