'For A Possession' in the Bible

"When you have come into the land of Canaan, which I give to you for a possession, and I put a spreading mildew in a house in the land of your possession,

You may make them an inheritance for your children after you, to hold for a possession; of them may you take your slaves forever: but over your brothers the children of Israel you shall not rule, one over another, with harshness.
