19 Melchizedek blessed Abram with this blessing: "Blessed be Abram by God Most High, Creator of heaven and earth. 20 And blessed be God Most High, who has defeated your enemies for you." Then Abram gave Melchizedek a tenth of all the goods he had recovered.

(Read Genesis 14:21-24)

Observe the king of Sodom's grateful offer to Abram, Give me the souls, and take thou the substance. Gratitude teaches us to recompense to the utmost of our power, those that have undergone fatigues, run hazards, and been at expense for our service and benefit. Abram generously refused this offer. He accompanies his refusal with a good reason, Lest thou shouldest say, I have made Abram rich: which would reflect upon the promise promise and covenant of God, as if He would not have enriched Abraham without the spoils of Sodom. The people of God must, for their credit's sake, take heed of doing any thing that looks mean or mercenary, or that savors of covetousness and self-seeking. Abraham can trust the Possessor of Heaven and earth to provide for him.
