And his mother answering said It is uncertain if Elisabeth spoke this by inspiration. But when Zacharias saw the punishment inflicted on him for being too slow in believing, he probably informed his wife by writing what the angel had enjoined respecting the name, (ver. 13,) otherwise he would not have obeyed the command of God. Why this name was given to the Baptist by divine authority, I have already explained. The relatives, though unacquainted with the reason, are affected by the strangeness of the occurrence, particularly as they conjecture it did not take place without design.

Shall be called John - This was the name which the angel had said should be given to him, of which Zechariah had probably informed Elizabeth by writing.

Not so; but he shall be called John - This is the name which the angel desired should be given him, Luke 1:13, and of which Zacharias by writing had informed his wife. There is something very remarkable in the names of this family. Zachariah, זכריהו the memory or memorial of Jehovah; יהו yeho, at the end of the word, being contracted for יהוה Yehovah, as in many other names. Elisabeth, אליסבה the Sabbath or rest of my strong God: names probably given them by their parents, to point out some remarkable circumstance in their conception or birth. And John, which should always be written Jehochanan or Yehochanan, יהוחנן the grace or mercy of Jehovah: so named, because he was to go before and proclaim the God of all grace, and the mercy granted through him to a lost world. See John 1:29; see also Luke 3:16, and Mark 1:4.

And his mother answered and said,.... That is, Elisabeth:
not so, but he shall be called John; knowing that this was the name wherewith the angel said he should be called; either by divine revelation, she being filled with the Holy Ghost, Luke 1:41 or by information of her husband, who, doubtless, in writing, gave her an account of all that the angel had said unto him.

His mother said - Doubtless by revelation, or a particular impulse from God.
