Luke 1:59-63

59It happened that on the eighth day they came to circumcise the child [as required by the Law], and they intended to name him Zacharias, after his father;

60but his mother answered, “No indeed; instead he will be called John.”

61And they said to her, “None of your relatives is called by that name.”

62Then they made signs to his father, as to what he wanted him called.

63And he asked for a writing tablet and wrote as follows, “His name is John.” And they were all astonished.
