'Hired' in the Bible

In that day [when foreign armies swarm the land] the Lord will shave with a razor, hired from the regions beyond the Euphrates (that is, with the king of Assyria), [that razor will shave] the head and the hair of the legs; and it will also remove the beard [leaving Judah stripped, shamed and scorned].

‘Why have we fasted,’ they say, ‘and You do not see it?Why have we humbled ourselves and You do not notice?’Hear this [O Israel], on the day of your fast [when you should be grieving for your sins] you find something you desire [to do],And you force your hired servants to work [instead of stopping all work, as the law teaches].
