'Labor' in the Bible

Likewise at the same time said I to the people, "Let everyone 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 may God shake out every man from his house, and from his labor, that doesn't perform this promise; even thus be he shaken out, and emptied." All the assembly said, "Amen," and praised Yahweh. The people did according to this promise.
