I have lifted up my hand. - This is a serious matter with Abram. Either before, or then and there, he made an oath or solemn asseveration before God, with uplifted hand, that he would not touch the property of Sodom. He must have felt that there was danger of moral contamination in coming into any political relationship with the cities of the vale. "The Lord, the Most High God, the Founder of heaven and earth." In this conjunction of names Abram solemnly and expressly identifies the God of himself and of Melkizedec in the presence of the king of Sodom. The Most High God of Melkizedec is the God of the first chapter of Genesis, and the Yahweh of Adam, Noah, and Abram.

I have lift up mine hand - The primitive mode of appealing to God, and calling him to witness a particular transaction; this no doubt generally obtained among the faithful till circumcision, the sign of the covenant, was established. After this, in swearing, the hand was often placed on the circumcised part; see Genesis 24:2, Genesis 24:9.

And Abram said to the king of Sodom,.... In reply to his request:

I have lifted up mine hand unto the Lord; which was both a gesture of praying and of swearing, and both may be intended here; when he set out on his expedition, it is very probable he prayed to God for success, and swore that if he prospered him, that he would receive no profit or advantage from it to himself; or now in the presence of Melchizedek he lift up his hands and swore that he would take none of the goods he had recovered to his own line; and in this form of praying or swearing, he makes use of the same epithets of God Melchizedek had just used:

the most high God, the possessor of heaven and earth: having his heart struck with those just and glorious representations of God, and awed with a sense of such a glorious Being, and being forward to learn and retain everything that tended to make for the glory of God.

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,

14:22 I have lift up mine hand to the Lord that I will not take anything - Here Observe, The titles he gives to God, the most high God, the possessor of heaven and earth - The same that Melchizedek had just now used. It is good to learn of others how to order our speech concerning God, and to imitate those who speak well in divine things. The ceremony used in this oath; I have lift up my hand - In religious swearing we appeal to God's knowledge of our truth and sincerity, and imprecate his wrath if we swear falsely; and the lifting up of the hands is expressive of both. Lest thou shouldst say, I have made Abram rich - Probably, Abram knew the king of Sodom to be a proud and scornful man, and one that would be apt to turn such a thing as this to his reproach afterwards, and when we have to do with such men, we have need to act with particular caution.

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.
