When he renamed himself this , what did people call out when they wanted to get his attention?

I guess it’s possible that they didn’t call him at all, that they just walked up and tapped him lovingly on his shoulder, or sent a white dove with a message tied around it’s leg that said, “, I need to speak to you.”

But what if there was an emergency? I would hate to think that I had a little red dot from a sharpshooter on my forehead and no one could warn me just because they didn’t know what to call me.
