and I will have you swear by the LORD, the God of heaven and the God of earth, that you will not take a wife for my son from the daughters of the Canaanites among whom I am dwelling,
3. That thou shalt not take a wife. The kind of discipline which prevailed in Abraham’s house is here apparent. Although this man was but a servant, yet, because he was put in authority by the master of the family, his servile condition did not prevent him from being next in authority to his lord; so that Isaac himself, the heir and successor of Abraham, submitted to his direction.
Three things we may observe here concerning Abraham: - I. The care he took of a good son, to get him married, well married. It was high time to think of it now, for Isaac was about forty years old, and it had been customary with his ancestors to marry at thirty, or sooner, Gen 11:14, Gen 11:18, Gen 11:22, Gen 11:24.
Commenting on Genesis 24:1-9
And I will make thee swear by the Lord, the God of heaven, and the God of earth,.... The Maker and possessor of heaven and earth, by whom Abraham used to swear whenever he did, and by whom only men should swear, see Gen 14:22.
