Circumcision the Sign of the Covenant
171 And Abram is a son of ninety and nine years, and Jehovah appeareth unto Abram, and saith unto him, 'I 'am' God Almighty, walk habitually before Me, and be thou perfect; 2 and I give My covenant between Me and thee, and multiply thee very exceedingly.'
Matthew Henry's Commentary on Genesis 17:1-2
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.
