'For A Possession' in the Bible

When you come into the land of Canaan which I give you for a possession, and I put the plague of leprosy in a house in the land of your possession,

And you shall take them as an inheritance for your sons after you, to hold for a possession; you may lay service on them forever. But you shall not rule over your brothers, the sons of Israel, over one another, with harshness.
