Midrash sur La Genèse 18:23

R. Levi said: Why did the Holy One give a revelation to Abraham? Because he had reflected in his heart about the generation of the flood, and said: It is impossible that there are not some righteous ones among them. You yourself know that it is so. THEN THE LORD SAID: SHALL I HIDE FROM ABRAHAM < WHAT I AM DOING >? What did < Abraham > answer him (in Gen. 18:23)? WILL YOU ALSO DESTROY THE RIGHTEOUS WITH THE WICKED?

And the two angels came to Sodom at evening (Gen. 19:1). What is written before this verse? And Abraham drew near and said, “Wilt Thou sweep away the righteous with the wicked?” (Gen. 18:23). R. Phinehas the priest, the son of Hama, stated: Certainly the Holy One, blessed be He, does not desire to find any of His creatures guilty, for it is said: I have no pleasure in the death of him that dieth (Ezek. 18:32). Furthermore it says: For Thou are not a God that hath pleasure in wickedness (Ps. 5:4); and: As I live, saith the Lord Eternal, I have no pleasure in the death of the wicked (Ezek. 33:11). What does the Holy One, blessed be He, take pleasure in doing? In proving the righteousness of His creatures, as it is said: The Lord was pleased, for His righteousness’ sake (Isa. 42:21). Proof of this is that even when mankind sins against the Holy One, blessed be He, and provokes him to anger, He relents and seeks an advocate to plead in their behalf. In fact, He suggests the arguments the advocate can employ. Hence, you find that at the time of Jeremiah, He proclaimed: Run ye, to and fro, through the streets of Jerusalem, and see now and know, and seek in the broad places thereof, if ye can find a man. If there be any who doeth justly, that seeketh truth, and I will pardon her (Jer. 5:1).

Similarly, after the Sodomites had transgressed, He revealed His intentions to Abraham in order to discover something to their credit, as it is said: And the Lord said: “Shall I hide from Abraham?” Abraham began to plead in their behalf, as it is said: And Abraham drew near and said: “Wilt Thou, indeed, sweep away the righteous with the wicked?” (Gen. 18:23). Drew near is an expression used to indicate prayer, as is said: And it came to pass, at the time of the offering of the evening offering, that Elijah the prophet drew near and said: “O Lord, the God of Abraham, of Isaac, and of Israel” (I Kings 18:36).
