It is no small confirmation of the condition of Abram at this time, if we read aright what follows in the very next: Genesis 16.
Undoubtedly Sarah was more to blame than Abram: there was haste through manifest want of faith in short; and consequently Hagar was given to her husband, and the fruits of the connection soon appeared. As always, she who was most to blame suffered the most. It was not so much Abram as Sarah who smarted through her folly about her maid. But we have again in this chapter the faithfulness of God even in the case of Hagar, who is told to return to her mistress and humble herself before her.
Jehovah here still carries on the prophetic testimony through His angel, and draws out the remarkable prefiguration of the Bedouins, who remain to this day a minor witness, but none the less a true one, of the truth of God’s word.
