Gevurot Meyruach Hakodesh 9:4-6

And he fell on the ground, and heard a kol (voice), saying to him, Sha'ul, Sha'ul, why are you persecuting me? And he said, Who are you, Adoni? And he said, I am Yehoshua/Yeshua upon whom you bring redifah. But get up and enter into the city, and it shall be told to you what it is necessary for you to do.
