'Labor' in the Bible

Likewise at the same time said I unto the people, Let every one with his servant lodge within Jerusalem, that in the night they may be a guard to us, and may labor in the day.

Also I shook out my lap, and said, So God shake out every man from his house, and from his labor, that performeth not this promise; even thus be he shaken out, and emptied. And all the assembly said, Amen, and praised Jehovah. And the people did according to this promise.
