John Gill Commentary Luke 1:60

"And his mother answered and said, Not so; but he shall be called John." — Luke 1:60 (ASV)

And his mother answered and said
That is, Elisabeth:

not so, but he shall be called John ;
knowing that this was the name with which 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.
