1 Chronicles 1:29-31 -

Contain the list of Ishmael's sons, twelve in number. The names in the Authorized Version and in the Hebrew text are identical respectively with those in Genesis 25:1 , Genesis 25:3-15 , except that for Hadar there we read Hadad here. In the Septuagint we have Idouma, Choudan, Iettar here, for Douma, Choddan, and Ietur there. At the close of this list in Genesis we have joined on to "these are the sons of Ishmael," the clauses, "and these are their names, by their towns, and by their castles; twelve princes according to their nations. And these are the years of the life of Ishmael, an hundred and thirty and seven years: and he gave up the ghost and died; and was gathered unto his people. And they dwelt from Havilah unto Shur, that is before Egypt, as thou goest toward Assyria: and he died in the presence of all his brethren."
