'Purchase' in the Bible

If you make a sale to your neighbor or a purchase from him, do not cheat one another.

You are to make the purchase from your neighbor based on the number of years since the last Jubilee. He is to sell to you based on the number of remaining harvest years.

Your male and female slaves are to be from the nations around you; you may purchase male and female slaves.

You may also purchase them from the foreigners staying with you, or from their families living among you—those born in your land. These may become your property.

If many years are still left, he must pay his redemption price in proportion to them based on his purchase price.
