¹ If the Lord doesn't build the house,
    the builders are working for nothing.
If the Lord doesn't guard the city,
    the guards are watching for nothing.
² It is no use for you to get up early
    and stay up late,
working for a living.
    The Lord gives sleep to those he loves.
³ Children are a gift from the Lord;
    babies are a reward.
⁴ Children who are born to a young man
    are like arrows in the hand of a warrior.
⁵ Happy is the man
    who has his bag full of arrows.
They will not be defeated
    when they fight their enemies at the city gate.
