Psalms 127:1-2

¹If people are building a house without knowing whether it is Yahweh's will to build it, they are building it in vain. Similarly, if Yahweh does not protect a city, it is useless for guards/sentries to stay awake to tell people if their enemies come to attack it.

²It is also useless to arise very early and go to sleep late at night in order that you can work hard all day to earn money to buy food, because Yahweh gives food to those whom he loves.
