'For A Possession' in the Bible

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

And ye shall make them an inheritance for your children after you, to hold for a possession; of them shall ye take your bondmen for ever: but over your brethren the children of Israel ye shall not rule, one over another, with rigor.
