Genesis 24:3

I will make thee swear - See note on Genesis 24:9.

Of the Canaanites - Because these had already been devoted to slavery, etc., and it would have been utterly inconsistent as well with prudence as with the design of God to have united the child and heir of the promise with one who was under a curse, though that curse might be considered to be only of a political nature. See the curse of Canaan, Genesis 9:25 (note).

The appeal is to God as "Yahweh, God of heaven and God of the earth." Yahweh is the personal name of God, which is properly used by those who are in fellowship with him. He is the Author of all being, and therefore of heaven and earth; and hence the arbiter of the destiny of the oath-taker, both in spiritual and material things, both in this life and in what is to come. "Not of the daughters of the Kenaanite," a race sinking fast into ungodliness and unrighteousness, doomed to extirpation, to whom the promised seed is to succeed. The kindred of Abraham were Shemites, Hebrews, and still retained some knowledge of the true God, and some reverence for him and his will. The experienced elder of Abraham's house does not wish to bind himself by an oath to what it may be impossible to fulfill. He makes the supposition of the unwillingness of the bride whom he may select, and obtains a quittance from his oath in that ease. The patriarch, however, charges him not to bring his son back to the land of his fathers, and expresses his confidence in the God of promise, that he will direct his servant to the suitable wife for his son. "His angel" Genesis 16:7. This is the Lord in the function of an angel or messenger opening the way for the servant of Abraham. He does not make any appearance to the servant, though a superintending Providence is strikingly displayed in the whole affair. The faithful elder now understands and takes the required oath.
