What did Alma Sr. do when he found out that an angel struck Alma Jr. so he couldn't speak or move his hands?

He rejoiced and gathered everyone to see what God did to his son.

They rehearsed unto his father all that had happened unto them; and his father rejoiced, for he knew that it was the power of God. And he caused that a multitude should be gathered together that they might witness what the Lord had done for his son. Mosiah 27:20-21
