Psalm 127:1-2

Expanded Bible

127 If the Lord doesn’t build the house,
    the builders are working ·for nothing [in vain; without purpose].
If the Lord doesn’t guard the city,
    the guards are watching ·for nothing [in vain; without purpose].
² It is ·no use [in vain; without purpose] for you to get up early
    and stay up late,
·working for a living [^Leating the bread of hardship/pain].
    The Lord ·gives sleep to those he loves [or provides for those he loves while they sleep].
