Put his hand under the thigh of Abraham - This form of swearing has greatly puzzled the commentators; but it is useless to detail opinions which I neither believe myself, nor would wish my readers to credit. I believe the true sense is given in the Targum of Jonathan ben Uzziel, and that called the Jerusalem Targum. In the former it is said, Put now thy hand בגזית מהולתי bigzirath mehulathi, in sectione circumcisionis meoe; in the latter תחות ירך קימי techoth yerech keyami, sub femore foederis mei. When we put the circumstances mentioned in this and the third verse together, we shall find that they fully express the ancient method of binding by oath in such transactions as had a religious tendency. 1. The rite or ceremony used on the occasion: the person binding himself put his hand under the thigh of the person to whom he was to be bound; i.e., he put his hand on the part that bore the mark of circumcision, the sign of God's covenant, which is tantamount to our kissing the book, or laying the hand upon the New Testament or covenant of our Lord Jesus Christ. 2. The form of the oath itself: the person swore by Jehovah, the God of heaven and the God of the earth. Three essential attributes of God are here mentioned:

1. His self-existence and eternity in the name Jehovah.

2. His dominion of glory and blessedness in the kingdom of heaven.

3. His providence and bounty in the earth.

The meaning of the oath seems to be this: "As God is unchangeable in his nature and purposes, so shall I be in this engagement, under the penalty of forfeiting all expectation of temporal prosperity, the benefits of the mystical covenant, and future glory." An oath of this kind, taken at such a time, and on such an occasion, can never be deemed irreligious or profane. Thou shalt swear by his name - shalt acknowledge and bind thyself unto the true God, as the just Judge of thy motives and actions, is a command of the Most High; and such an oath as the above is at once (on such an occasion) both proper and rational. The person binding himself proposes for a pattern the unchangeable and just God; and as He is the avenger of wrong and the punisher of falsehood, and has all power in the heavens and in the earth, so he can punish perjury by privation of spiritual and temporal blessings, by the loss of life, and by inflicting the perdition due to ungodly men, among whom liars and perjured persons occupy the most distinguished rank. Our ideas of delicacy may revolt from the rite used on this occasion; but, when the nature of the covenant is considered, of which circumcision was the sign, we shall at once perceive that this rite could not be used without producing sentiments of reverence and godly fear, as the contracting party must know that the God of this covenant was a consuming fire.

And the servant put his hand under the thigh of Abraham his master,.... Or "then" or "therefore the servant", &c. (n) being satisfied of the nature and extent of his oath, and thoroughly understanding how he was to act upon it, readily took it by using this rite; see Gill on Genesis 24:2,

and sware to him concerning that matter; of taking a wife to his son, engaging to do everything he had directed and enjoined him relative to it.

(n) "posuit ergo", V. L. "igitur", Tigurine version; "itaque", Junius & Tremellius, Piscator; "ita", Drusius; "tum", Schmidt.

And the servant put his hand under the thigh of Abraham his master, and sware to him concerning that matter.

24:1-9 The effect of good example, good teaching, and the worship of God in a family, will generally appear in the piety, faithfulness, prudence, and affection of the servants. To live in such families, or to have such servants, both are blessings from God which should be highly valued, and thankfully acknowledged. But no concern in life is of greater importance to ourselves, to others, or to the church of God, than marriage. It therefore ought always to be undertaken with much care and prudence, especially with reference to the will of God, and with prayer for his direction and blessing. Where good parents are not consulted and regarded, the blessing of God cannot be expected. Parents, in disposing of their children, should carefully consult the welfare of their souls, and their furtherance in the way to heaven. Observe the charge Abraham gave to a good servant, one whose conduct, faithfulness, and affection, to him and his family, he had long known. Observe also, that Abraham remembers that God had wonderfully brought him out of the land of his birth, by the call of his grace; and therefore doubts not but He will prosper his care, not to bring his son thither again. God will cause that to end in our comfort, in which we sincerely aim at his glory.
