And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.
Abraham called ... circumcised. God was acknowledged in the name which, by divine command, was given for a memorial (cf. Genesis 17:19), and also in the dedication of the child, by administering the seal of the covenant (cf. Genesis 17:10-12). His birth is supposed by Wilton (Negeb) to have taken place at Eltolad, which may be rendered 'born of God,' or, 'a supernatural birth.'
