Luke 1:62

Zacharias also is questioned, and signs made to him, as it follows, And they made signs to the father, &c. But since unbelief had so bereft him of utterance and hearing, that he could not use his voice, he spoke by his hand-writing, as it follows, And he asked for a writing table, and wrote, saying, His name is John; that is, we give no name to him who has received his name from God.

For this reason there follows: And they made signs to his father, what he would have him called: they made signs, I say, to one deaf and mute, because, as Ambrose says, "incredulity had stolen from him both speech and hearing"; and yet they sought …

There was mercy in bringing her safely through her time of trial. There was mercy in making her the mother of a living child.
