16 These are the sons of Ish'mael and these are their names, by their villages and by their encampments, twelve princes according to their tribes.

Matthew Henry's Commentary on Genesis 25:16

Commentary on Genesis 25:11-18

(Read Genesis 25:11-18)

Ishmael had twelve sons, whose families became distinct tribes. They peopled a very large country that lay between Egypt and Assyria, called Arabia. The number and strength of this family were the fruit of the promise, made to Hagar and to Abraham, concerning Ishmael.
