'Possessor' in the Bible

And he blessed him, and said, Blessed be Abram of the most high God, possessor of heaven and earth:

And Abram said to the king of Sodom, I have lift up mine hand unto the LORD, the most high God, the possessor of heaven and earth,

And Abram said, O Lord Jehovah, what wilt thou give me, seeing I go childless, and he that shall be possessor of my house is Eliezer of Damascus?
