'Worked' in the Bible

It happened from that time forth, that half of my servants worked in the work, and half of them held the spears, the shields, and the bows, and the coats of mail; and the rulers were behind all the house of Judah.

They all built the wall and those who bore burdens loaded themselves; everyone with one of his hands worked in the work, and with the other held his weapon;

So we worked in the work: and half of them held the spears from the rising of the morning until the stars appeared.

It happened, when all our enemies heard [of it], that all the nations that were about us feared, and were much cast down in their own eyes; for they perceived that this work was worked of our God.
