Luke 1:22
When he came out, he could not speak to them. They realized he had seen a vision in the temple, for he kept making signs to them but remained unable to speak — the people's recognition that Zechariah had seen a vision communicates their theological literacy: a mute priest who keeps making signs has clearly experienced something supernatural in the Holy Place. The making of signs (dianeuōn) is both his inability and his communication — Zechariah is trying to tell the congregation what he cannot verbally speak.
