Gen 17:20

“And as for Ishmael, I have heard thee, &c. Took notice of his prayer for him, and accepted of and would answer him, and did, as follows: behold, I have blessed him; determined in his mind to bless him, promised to bless him, Gen 16:10; had blessings laid up and in reserve for him: and will make him fruitful, and will multiply him exceedingly; as he did, many of the Arabian nations, the Hagarenes, Saracens, and Turks, all springing from him: twelve princes shall he beget; whose names are given, Gen 25:13; and their number there exactly agrees with this prophecy. Melo (s), the Heathen writer above mentioned, says, that Abraham, of his other wife, the Egyptian servant (that is, Hagar), begat twelve sons, which he mistakes for twelve sons of Ishmael, his son by Hagar; and, adds he, these going into Arabia, divided the country among them, and were the first that reigned over the inhabitants of it; hence down to our times the kings of the Arabians have twelve names like to those. So the Saracens were divided into twelve tribes, of which there were so many "phylarchi", or governors; and the Turks also are divided into the same number of tribes (t). And I will make him a great nation; as the nation of the Turks especially is; and the Turkish empire is frequently called in Jewish writings the kingdom of Ishmael, as the Arabic language is called the Ishmaelitish language.

“Twelve princes shall he beget, etc. - See the names of these twelve princes, Gen 25:12-16. From Ishmael proceeded the various tribes of the Arabs, called also Saracens by Christian writers. They were anciently, and still continue to be, a very numerous and powerful people. "It was somewhat wonderful, and not to be foreseen by human sagacity," says Bishop Newton, "that a man's whole posterity should so nearly resemble him, and retain the same inclinations, the same habits, and the same customs, throughout all ages! These are the only people besides the Jews who have subsisted as a distinct people from the beginning, and in some respects they very much resemble each other 1. The Arabs, as well as the Jews, are descended from Abraham, and both boast of their descent from the father of the faithful. 2. The Arabs, as well as the Jews, are circumcised, and both profess to have derived this ceremony from Abraham. 3. The Arabs, as well as the Jews, had originally twelve patriarchs, who were their princes or governors. 4. The Arabs, as well as the Jews, marry among themselves, and in their own tribes. 5. The Arabs, as well as the Jews, are singular in several of their customs, and are standing monuments to all ages of the exactness of the Divine predictions, and of the veracity of Scripture history. We may with more confidence believe the particulars related of Abraham and Ishmael when we see them verified in their posterity at this day. This is having, as it were, ocular demonstration for our faith." See Bp. Newton's Second Dissertation on the Prophecies, and See note on Gen 16:12.”
