Adam Clarke on Genesis 24:4

My country - Mesopotamia, called here Abraham's country, because it was the place where the family of Haran, his brother, had settled; and where himself had remained a considerable time with his father Terah. In this family, as well as in that of Nahor, the true religion had been in some sort preserved, though afterwards considerably corrupted; see Gen 31:19.

And take a wife unto my son - A young man in Bengal is precisely in the same circumstances as Isaac; he has nothing to do in the choice of a wife; parents employ others to seek wives for their sons. Those who leave their homes in search of employment always marry their children in their own country, and among their acquaintance at home; never among the people with whom they reside. In Asiatic countries this custom has prevailed from the infancy of the human race. See Ward's Hindoo Customs.
