Melchizedek, king and priest

Genesis 14:18-20

And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God.

And he blessed him, and said, Blessed be Abram of the most high God, possessor of heaven and earth: And blessed be the most high God, which hath delivered thine enemies into thy hand.

And he gave him tithes of all.

Genesis 14:21-24

And the king of Sodom said unto Abram, Give me the persons, and take the goods to thyself.

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, That I will not take from a thread even to a shoelatchet, and that I will not take any thing that is thine, lest thou shouldest say, I have made Abram rich: Save only that which the young men have eaten, and the portion of the men which went with me, Aner, Eshcol, and Mamre; let them take their portion.

Entangling alliances do not include a confederacy (a military agreement), and they do include commerce.
