And they made war with the Hagarites,.... Before mentioned, Ch1 5:19. with Jetur, and Nephish: with the posterity of these men, who were sons of Ishmael, Gen 25:15 and so was Nodab; perhaps the same with Kedemah, mentioned along with the other two there; so Hillerus (z) thinks. (z) Onomastic. Sacr. p. 554.
