Another time the emperor said to him: I wish to see your God. You can't, R. Yehoshua replied. But I will, the emperor said. So he placed the emperor facing the sun at the summer solstice and told him to look at it. I can't, the emperor said. R. Yehoshua said: the sun is but one of the ministers attending to God; if you can't even look at it then how can you presume to look upon the divine presence?
Another time the emperor said: I will prepare a feast for your God. You can't. Why not? His attendants are too numerous. But I will. Ok, R. Yehoshua said, prepare it on the spacious banks of Rebita. The emperor spent the six months of summer preparing and a tempest came and swept it all away; he then spent the six months of winter preparing and rains came and washed it all away. He asked: what is the meaning of this? R. Yehoshua said: they are just the sweepers and sprinklers that come before God. Then, the emperor said, I cannot do it.
The emperor's daughter once said to him: your God is a carpenter ("who lays the beams of his upper chambers in the waters"), so ask him to make for me a spool. Very well, he said, and he prayed. She was smitten with leprosy, and, per Roman tradition, was removed to the open square and given a spool to wind skeins on. (This was apparently so people would see her and pray for her.) One day R. Yehoshua passed by and said to her: my God has given you a beautiful spool! She said: I pray you, ask him to take back what he has given me. He replied: our God grants a request, but when granted he never takes it back. (59b-60a)
