'Expert' in the Bible

When the king of Moab realized that the battle was going strongly against him, he took 700 expert swordsmen to attempt to break through to the king of Edom, but was unable to do so.

And he took away all the people of Jerusalem and all the chiefs and all the men of war, ten thousand prisoners; and all the expert workmen and the metal-workers; only the poorest sort of the people of the land were not taken away.

And all the men of war, seven thousand of them, and a thousand expert workmen and metal-workers, all of them strong and able to take up arms, the king of Babylon took away as prisoners into Babylon.
