Midrasz do Hioba 26:7

R. Jochanan said in the name of R. Elazar b. R. Simon: "Wherever you find something said by R. Eliezer, the son of R. Jose, the Galilian, in the way of homeletics, make thy ear like the hopper [to receive his words]." (Deut. 7, 7) The Lord did not set His love upon you nor choose you, because ye were more in number than any people, etc. The Holy one, praised be He! said unto Israel: "I love you, because at the time when I even overwhelm you with dignity, ye are belittling yourself before Me. For I gave dignity unto Abraham and he [in return] said (Gen. 18, 27) Who am I but dust and ashes. I did the same unto Moses and Aaron and they [in return] said (Ex. 16, 7) And what are we. Unto David, and he said (Ps. 22, 7) But I am a worm, and not a man. The other nations, however, behave differently; for when I gave dignity unto Nimrod, he then said (Gen. 11, 3) Come, let us build us a city. Unto Pharaoh, and he said (Ex. 5, 2) Who is the Lord? Unto Sennacherib, and he said (II Kings 18, 35) Who are they among all the gods of the countries, etc. Unto Nebuchadnezzar, and he said (Is. 14, 14) I will ascend above the heights of the clouds. Unto Chiram, King of Tyre, and he said (Ez. 28, 2) I sit in the seat of God, in the heart of the seas." Raba, and according to some authorities, R. Jochanan, said "The stand which the passage states was taken by Moses and Aaron is more [exhausting] than the one taken by Abraham; for concerning Abraham it is written, Who am but dust and ashes, while concerning Moses and Aaron, it is written, And what are we?" Raba, and according to others, R. Jochanan, said further: "The world would not have been in existence were it not for the sake of Moses and Aaron; for it is written here and what are we, and it is written elsewhere (Job 26, 7) He hangeth the earth over nothing."

R. Ila'a said: "The world would not have been able to exist were it not for the one who restrains himself in strife (keeps silent); as the passage says (Job 26, 7) Hangeth the earth over [for the sake of those who consider themselves as] nothing." R. Abahu said: "For the one who makes himself like nothing, as it is said (Deut. 33, 27) And underneath are the everlasting arms." R. Isaac said: "What is the meaning of the passage (Ps. 58, 2) Do ye indeed speak as a righteous company? Do ye judge with equity the sons of men? i.e., with what shall a man occupy himself in this world? He should make himself dumb. One might think that even to study the Torah one is allowed to make himself dumb; it therefore says, speak as righteous. Perhaps one will think that one is allowed to exalt himself [with the Torah]. The passage therefore says, Judge with equity, the sons of men."
