14. And Mishma, and Dumah, and Massa,
15. Hadad, and Tema, Jetur, Naphish, and Kedemah:
16. These are the sons of Ishmael, and these are their names, by their towns, and by their encampments; twelve princes according to their nations.
17. And these are the years of the life of Ishmael, a hundred and thirty-seven years: and he breathed his last and died; and was gathered unto his people.
18. And they dwelt from Havilah unto Shur, that is beside Egypt, as you go toward Assyria: and he died in the presence of all his brethren.
19. And these are the generations of Isaac, Abraham's son: Abraham begat Isaac:
