John Wesley on Genesis 24:1

Abraham's pious care concerning his son was, that he should not marry with a daughter of Canaan, but with one of his kindred because he saw, the Canaanites were degenerating into great wickedness, and knew, that they were designed for ruin: would not marry his son among them, lest they should be either a snare to his soul, or, at least, a blot to his name. Yet he would not go himself among his kindred, lest he should be tempted to settle there: this caution is given, Ge 24:6, and repeated, Ge 24:8. Parents, in disposing of their children, should carefully consult their furtherance in the way to heaven.
