Genesis 14:22

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.

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.

14:22 I have lift up mine hand to the Lord that I will not take anything — Here Observe, (1.) 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. (2.) 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.
