'Occupation' in the Bible

When Pharaoh addresses you and asks, ‘What is your occupation?’

Then Pharaoh asked his brothers, “What is your occupation?”And they said to Pharaoh, “Your servants, both we and our fathers, are shepherds.”

For all his days are filled with grief, and his occupation is sorrowful; even at night, his mind does not rest. This too is futile.

and being of the same occupation, stayed with them and worked, for they were tentmakers by trade.
