Midrasz do Diwrej ha-jamim II 25:18

(Devarim 3:23) "And I supplicated (va'ethchanan) the L-rd": "Va'ethchanan" is a term of entreaty. "at that time to say": Let "to say" not be written. The intent is: Make it known to me whether I will enter the land or not. "Adonai": the L-rd (adon) of all who enter the world. "Elokim": With (the attribute of) justice did You create the world. "You have begun": You have begun to open the door for Your servant, in my entering the inheritance of the children of Reuven and the children of Gad. Variantly: You have profaned (i.e., broken) Your oath. You wrote in Your Torah (Shemot 22:19) "He who sacrifices to a god shall be condemned." Yet your children served idolatry and I sought mercy from You, and You forgave them. (Devarim, Ibid.) "to show Your servant": miracles and mighty acts, viz. (Shemot 3:3) "I shall turn aside and I shall see, etc." (Devarim, Ibid.) "Your greatness": This is the attribute of Your goodness, as it is written (Bamidbar 14:17) "And now, let the power of the L-rd be made great." (Devarim, Ibid.) "And Your (mighty) hand": This is Your right hand, which is stretched out to all who enter the world, viz. (Shemot 15:6) "Your right hand, O L-rd, is exalted in power," and (Psalms 44:4) "Your right hand, and Your arm, and the light of Your countenance." (Devarim, Ibid.) "mighty": For You subdue with mercy the attribute of justice, viz. (Michah 7:18) "Who is a G-d like You, forgiving transgression and passing by offense," (19) "He will return and be merciful to us, He will subdue our transgressions," (20) "You will give truth to Yaakov," and (Isaiah 45:23) "I have sworn by Me: From My mouth has gone forth righteousness, a word that will not turn back." (Devarim, Ibid.) "Who is mighty in heaven and earth": The attribute of flesh and blood — He who is greater than his neighbor nullifies his neighbor's decree. But You — who can overrule You? And thus is it written (Iyyov 23:13) "And He is One, and who can turn Him back?" R. Yehudah b. Bava says: Not as the measure of the Holy One Blessed be He is the measure of flesh and blood. The measure of flesh and blood: A man registered in the royal codex — even if he gives great sums, he cannot extricate himself from it. But You say: Repent, and I will accept, as it is written (Isaiah 44:22) "I have wiped away your offenses like a cloud, your sins, like a mist." Variantly: "Who is G-d in heaven and earth, etc." — But perhaps, outside of heaven and earth, there is! It is, therefore, written (Devarim 4:39) "And you shall know this day and you shall return it to your heart … there is no other" — anywhere! (Ibid.) "who can do as Your deeds and as Your (acts of) strength": "as Your deeds" — in Egypt. "as Your strength" — at the (splitting of the) sea. Variantly: "as Your deeds" — at the sea. "as Your strength" — at the streams of Arnon. (Ibid. 25) "Let me pass over na and see"." "Na" is a term of imploration. "the good land across the Jordan": As per R. Yehudah: The land of Canaan is "good," and not the inheritance of the children of Reuven and the children of Gad. "this good mountain": Jerusalem. "and the Levanon": the Temple, viz. (Zechariah 11:1) "Open your doors, O Levanon!" and (Isaiah 10:34) "And the Levanon shall fall by a mighty one (Nevuchadnezzar)." Others say: "Levanon" — these are its (Israel's) kings, as in (Ezekiel 17:3) "He came to the Levanon and he took its kings," and (II Chronicles 25:18) "The thistle (i.e., the king) etc."
