Psalms 127:1
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
Except the Lord build the house, they labour in vain that build it (note: Heb. are builders of it in it): except the Lord keep the city, the watchman waketh but in vain.
A song of ascents. Of Solomon. Unless the LORD builds the house, its builders labor in vain; unless the LORD protects the city, its watchmen stand guard in vain.
