Genesis 14:23

a thread … a shoelatchet Not the most trifling thing, not even, the lace for a sandal, will Abram take. The fact that Abram has already (Genesis 14:20) given to Melchizedek a tithe of all the spoil, strictly speaking, conflicts with his refusal, in this verse, to take any share of the spoil. Probably this discrepancy is an indication that the episode of Melchizedek (Genesis 14:18) has been introduced from a distinct source of tradition.

lest thou shouldest say, &c. Abram emphasizes the fact, (1) that he did not make war in order to make himself richer or stronger: (2) that he and his household are not going to be beholden to the king of Sodom and the people of the Plain. What he had done, was not for gain, but for the safety of his relative Lot. Contrast, however, Abraham's acceptance of gifts, in Genesis 12:16; Genesis 20:14-16, under different cumstances.
