John Chrysostom
Then the angel proclaims the future way of life for the son to be born to Hagar, stating that he will be like a wild ass among men: his hand shall be against everyone, and everyone's hand shall be against him; he will dwell in the presence of his brothers. This prediction reveals that he will be a man of strength, a warrior, and will toil greatly in the soil. Therefore, in all that has transpired concerning the servant, can you not see the glory of the patriarch Abraham? Such concern for the servant reflects the Lord's favor toward this faithful man. After delivering this message and the good news to Hagar, the angel subsequently departed.
