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.
Isaac - See the reason and interpretation of this name in the note on Genesis 17:7 (note).
And Abraham called the name of his son that was borne unto him, whom Sarah bare to him, Isaac. Which is the name he was directed to give him, Genesis 17:19; and he remembers the order, and is obedient to it; the reason of which name, which signifies laughter, was on account of his laughing for joy at the promise made him, as well as there might be afterwards a further reason for it, from Sarah's laughing through distrust; and it might presignify the joy and laughter that would be expressed by others at his birth; and perhaps also that he would be the object of the laughter and derision of his brother; such a number of events agreeing with his name.
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).
