'Sold' in the Bible

“If your fellow Israelite, a Hebrew man or woman, is sold to you, and serves you for six years, then in the seventh year you shall set him free [from your service].

The Lord will bring you back to Egypt in ships, by the way about which I said to you, ‘You will never see it again!’ And there you will offer yourselves for sale to your enemies as male and female slaves, but there will be no one to buy you.

“How could one chase a thousand,And two put ten thousand to flight,Unless their Rock had sold them,And the Lord had given them up?
