4 As for me, my agreement is made with you, and you will be the father of nations without end. 5 No longer will your name be Abram, but Abraham, for I have made you the father of a number of nations. 6 I will make you very fertile, so that nations will come from you and kings will be your offspring.
Matthew Henry's Commentary on Genesis 17:4-6
Commentary on Genesis 17:1-6
(Read Genesis 17:1-6)
The covenant was to be accomplished in due time. The promised Seed was Christ, and Christians in him. And all who are of faith are blessed with faithful Abram, being partakers of the same covenant blessings. In token of this covenant his name was changed from Abram, "a high father," to Abraham, "the father of a multitude." All that the Christian world enjoys, it is indebted for to Abraham and his Seed.
