Genesis 16:12

And he will be a wild man; his hand will be against every man and every man's hand against him; and he shall dwell in the presence of all his brethren. Because the fruit of her body was the seed of Abram, Hagar was to return to her mistress, and for the sake of his father the promise of innumerable progeny is given. The very name of her son is given her, namely, Ishmael, "God hears," because the Lord had heeded the cry of her misery and distress. This son should, moreover, unlike his mother, be free from the oppression of men, as free as the wild ass of the deserts, wild-roving and untamable; and his descendants would be characterized by the ceaseless feuds between themselves and with their neighbors, as they dwelt in the presence of their brethren, of the children of Israel, to whom they were a constant menace and challenge. To this day the Ishmaelites are in unimpaired, free possession of the great peninsula lying between the Euphrates, the Isthmus of Suez, and the Red Sea, whence they have spread over wide districts in North Africa and Southern Asia.
