'Buy' in the Bible

You may buy food to eat and water to drink from them, paying with cash."'

You may spend the money to your heart's content to buy livestock, flocks, wine, strong drink, and whatever you desire. You and your household may eat there and rejoice in the presence of the LORD your God."

Finally, the LORD will bring you back to Egypt by ship, a place that I said you'd never see again. There you'll try to sell yourselves to your enemies as male and female slaves, but no one will buy you."
