Psalm 127:1-5

If the LORD does not build the house, the work of the builders is useless; if the LORD does not protect the city, it does no good for the sentries to stand guard. It is useless to work so hard for a living, getting up early and going to bed late. For the LORD provides for those he loves, while they are asleep. Children are a gift from the LORD; they are a real blessing. The sons a man has when he is young are like arrows in a soldier's hand. Happy is the man who has many such arrows. He will never be defeated when he meets his enemies in the place of judgment.
