R. Nathan ben Eleazar questioned R. Samuel. He said to him: How did the Holy One create the world? R. Samuel said to him: When the Holy One desired to create the world, he wrapped himself in light, as stated (in Ps. 104:2): PUTS ON LIGHT LIKE A GARMENT. He said to him: You have told me in a whisper. Why in a whisper? He said to him: Just as I received this tradition in a whisper, so I have transmitted it to you in a whisper. R. Tanhuma bar Abba said to him: Have we not already heard R. Isaac expounding it publicly?
