Genesis 14
Abram gave [Melchizedek] a tenth of everything. 21 The king of Sodom said to Abram, “Give me the captives; the goods you may keep.” 22 But Abram replied to the king of Sodom: “I have sworn to the Lord, God Most High, the creator of heaven and earth, 23 that I would not take so much as a thread or a sandal strap from anything that is yours, so that you cannot say, ‘I made Abram rich.’
Normally readers of the Bible focus on the spiritual significance of Abram's tithe. Here, I ask about its immediate political implications as well. The king of Sodom was Abram's ally in the war that liberated Abram's nephew Lot. On their way south after the victory, Melchizedek came out from Salem and met with Abram, giving him the blessing of El Elyon (God Most High). Abram responded by offering his tithe. Immediately after this the king of Sodom demanded to be given the war captives but would allow Abram to keep the other plunder. Abram refused on the ground that he had sworn not to receive anything at all from the king of Sodom. He has made this oath in the name of "the Lord, God Most High" (Yahweh El Elyon).
My question is this: Does this oath - combining the names by which Abram and Melchizedek related to God - imply that Abram is now both politically and religiously allied with Melchizedek, as opposed to his recent ally, the king of Sodom? Since Melchizedek is the king of the area's largest city, does Melchizedek's reception of Abram's tithe imply that Salem will protect Abram's clan from Sodom?
