13 And also of the son of the bondwoman will I make a nation, because he is thy seed.
13 I will make the son of the slave into a nation also, because he is your offspring."
13 And I will make a nation of the son of the slave woman also, because he is your offspring."
13 Regarding your maid's son, be assured that I'll also develop a great nation from him - he's your son too."
13 Yet I will also make a nation of the son of the bondwoman, because he is your seed."
13 But I will also make a nation of the descendants of Hagar's son because he is your son, too."

Commentary on Genesis 21:9-13
(Read Genesis 21:9-13)
Let us not overlook the manner in which this family matter instructs us not to rest in outward privileges, or in our own doings. And let us seek the blessings of the new covenant by faith in its Divine Surety. Ishmael's conduct was persecution, being done in profane contempt of the covenant and promise, and with malice against Isaac. God takes notice of what children say and do in their play; and will reckon with them, if they say or do amiss, though their parents do not. Mocking is a great sin, and very provoking to God. And the children of promise must expect to be mocked. Abraham was grieved that Ishmael should misbehave, and Sarah demand so severe a punishment. But God showed him that Isaac must be the father of the promised Seed; therefore, send Ishmael away, lest he corrupt the manners, or try to take the rights of Isaac. The covenant seed of Abraham must be a people by themselves, not mingled with those who were out of covenant: Sarah little thought of this; but God turned aright what she said.
