'Buy' in the Bible

You shall buy food from them with money so that you may [have something to] eat, and you shall also buy water from them with money so that you may [have something to] drink.

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.
