Jamieson, Fausset, and Brown - Commentary Critical and Explanatory on the Whole Bible
3, 4. Abraham called the name of his son … Isaac … and circumcised—God was acknowledged in the name which, by divine command, was given for a memorial (compare Genesis 17:19 ), and also in the dedication of the child by administering the seal of the covenant (compare Genesis 17:10-12 ).
John Calvin - Commentaries
**And Abraham called the name. Moses does not mean that Abraham was the inventor of the name; but that he adhered to the name which before had been given by the angel. This act of obedience, however, was worthy of commendation, since he not only ratified the word of God, but also executed his office as God’s minister. For, as a herald, he proclaimed to all, that which the angel had committed to his trust.
