Genesis 24:7
The LORD God of heaven, which took me from my father’s house, and from the land of my kindred, and which spake unto me, and that sware unto me, saying, Unto thy seed will I give this land; he shall send his angel before thee, and thou shalt take a wife unto my son from thence.
The assurance rests on what God had already done and sworn: He had taken Abraham from his father's house and from the land of his kindred, had spoken to him, and had sworn that to his seed He would give the land of Canaan. On that past call and that oath concerning the land and descendants Abraham grounded his confidence for the present task. Because God had so called and so promised, Abraham was confident that He would send His angel before the servant to guide the search for a wife for Isaac. That search was to be made among Abraham's kindred, while Isaac himself was to remain in Canaan and was not to be taken back to the country from which Abraham had come.
The restriction to kindred was a safeguard of faith, for a Canaanite wife was forbidden because the Canaanites were idolaters whose influence could draw Isaac away from God. Seeking instead a wife among kindred who believed in the true God protected Isaac and preserved the worship of the living God. Yet the commission was not absolute beyond willingness: if no suitable woman from the kindred would leave to come with the servant, the servant would be released from his oath. Remembering the promise, the servant prayed for clear direction when choosing among strangers in Haran, and his prayer for guidance together with the circumstances surrounding Rebekah confirmed that God had selected her.
Abraham's course in this stands as an example of parents guiding their children's affections and choosing suitable companions for them, rather than leaving the choice unguided. Parents have the responsibility to command their households after them, to teach children to respect parental authority, and to guide the affections of sons and daughters toward persons who would be suitable companions in marriage. That responsibility rebukes the notion that affections should not be guided or restrained, especially since Satan controls the affections of the young to a great extent. Isaac was prepared for such guidance by training that taught him to value obedience and showed him parental authority exercised in love for a child's welfare. He therefore loved noble obedience, respected and yielded to his father's judgment under God, and trusted God to direct the choice made through his father's experienced, God-fearing servant.
His submission makes the marriage an example for young people and children who profess to fear God: to seek God's guidance, to respect parental direction and judgment, and to seek God-fearing counsel in choosing a spouse. The marriage entered in that way brought lasting love and comfort.
