Rabbi Yehoshua uttered a Name of God and hovered between the sky and the earth. He said to them: Bring up to me bricks and mortar and I will build you a house here. They asked him: Where is the center of the world? Rabbi Yehoshua raised his finger and said to them: Here. They said to him: And who says that you are correct? He said to them: Bring ropes and measure.
