The emperor of Rome (I don't know which one) once said to R. Yehoshua ben
Hananiah: your God has been likened to a lion; show me this lion.
R. Yehoshua said: that was no ordinary lion but the lion of Belalil.
I will see it, the emperor said. So R. Yehoshua prayed and the lion set
out from its place. When it was 400 parasangs away it roared once and all
pregnant women miscarried and the walls of Rome fell. When it was 300
parasangs away it roared again and all the molars and incisors of men fell
out and the emperor fell from his throne to the ground. I beseech you, he
said, ask it to go home; R. Yehoshua prayed and it did.
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)
