Genesis 14:23

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:

Ver. 23. That I will not take from a thread.] Melchizedek, from God, had made Abram heir of all things; for, saith he, I am the priest of the most high God, possessor of heaven and earth, who hath sent me with this bread and wine, as by turf and twig, as by an earnest and a little for the whole, to give thee possession of both. Now, therefore, when the king of Sodom presently after offers him the goods he had taken, Abram would none; he was grown too great to accept of such an offer; God was his "exceeding great reward". Gen 15:1 Aquila non captat muscas .

Lest thou shouldst say, I have made Abram rich.] Occasion must not be given to any to speak the least evil of us, lest Christ be dishonoured: for every Christian quartereth arms with Christ. And if Abram do anything unbeseeming himself, Abram's God shall be blasphemed at Sodom.
