Luke 1:20-24

But since you didn't believe what I told you, you'll become dumb, unable to speak, until the appointed time when my words come true.”

Outside the people were waiting for Zechariah, wondering why he was taking so long in the Temple.

When eventually he came out, he wasn't able to speak to them. They realized he'd seen a vision in the Temple, for though he could make gestures, he was completely dumb.

After he'd finished his time of service, he went back home.

Some time later his wife Elizabeth became pregnant. She stayed at home for five months.
