'Labor' in the Bible

Trembling seized them there,agony like that of a woman in labor,

He gave their crops to the caterpillarand the fruit of their labor to the locust.

He waters the mountains from His palace;the earth is satisfied by the fruit of Your labor.

Man goes out to his workand to his labor until evening.

He broke their spirits with hard labor;they stumbled, and there was no one to help.

A Solomonic song of ascents.Unless the Lord builds a house,its builders labor over it in vain;unless the Lord watches over a city,the watchman stays alert in vain.
