Charles Ellicott Commentary Genesis 14:19

"And he blessed him, and said, Blessed be Abram of God Most High, possessor of heaven and earth:" — Genesis 14:19 (ASV)

Possessor. — Literally, creator, or framer. It is a poetical word, as are also those for “delivered” and “enemies.” The form of the blessing, moreover, is poetical, as it is arranged in parallel clauses.
