Rashi on Deuteronomy 3:24/רש"י על דברים ג׳:כ״ד

1אדני אלהים O LORD, GOD — O Thou Who art. merciful (ה׳) in judgment (אלהים) (cf. Sifrei Devarim 26:10).

2אתה החלות להראות את עבדך THOU DIDST BEGIN TO SHOW THY SERVANT an opening to stand and offer prayer, although the decree has been enacted; he said to Him: I learned to do so from Thee, for Thou didst say to me, (Exodus 32:10; cf. Rashi thereon) "And now, leave Me alone”. Was I, then, holding Thee? But Thou didst say this to open the door and to show that it depended upon me to pray for them. Just so do I think to act now (Sifrei Devarim 27:2).

3את גדלך [TO SHOW] THY GREATNESS — This means Thy attribute of goodness. Similarly it states, (Numbers 14:17, 18) "And now, I beseech Thee, let the strength of my Lord be great, [according as thou hast spoken, saying: The Lord is long-suffering and of much mercy, etc."].

4ואת ידך AND THY [STRONG] HAND — This refers to Thy right hand which is extended to all who enter the world (all human beings) [to receive them in penitence] (Sifrei Bamidbar 134:5).

5החזקה [THY] STRONG [HAND] — I speak of it as Thy strong hand, because by showing mercy Thou forcibly (בחזקה) subduest the attribute of strict justice (Sifrei Bamidbar 134:5).

6אשר מי אל וגו׳ FOR WHAT GOD IS THERE [… WHO CAN DO ACCORDING TO THY WORKS] — Thou art unlike a mortal king who has counsellors and assessors who would prevent him when he wishes to show kindness and to forgo, what is due to him: Thou, however, — there is none who can prevent Thee if Thou pardonest me and dost annul Thy decree (Sifrei Devarim 27:6). But according to its plain sense it means: "Thou hast begun to show Thy servant the war with Sihon and Og, as it is written, (Deuteronomy 2:31) “Behold I have begun to give [Sihon and his land] before thee"; let me behold also the war with the thirty-one kings of Canaan.
