Midrasch zu Dewarim 3:3

(Deut. 7:12:) AND IT SHALL COME TO PASS IF YOU HEED <THESE STATUTES>. What is written above on the matter (in Deut. 7:7)? IT WAS NOT BECAUSE YOU WERE THE MOST NUMEROUS OF ALL THE PEOPLES, <THAT THE LORD DESIRED YOU AND CHOSE YOU. RATHER YOU WERE THE LEAST OF ALL THE PEOPLES>. The Holy One said to Israel: It was not because you were the most numerous of all the nations, and it was not because you fulfilled more commandments than they, for they magnify my name more than you.¹²Tanh., Deut. 3:3. Thus it is stated (in Mal. 1:11–12): FOR FROM THE RISING OF THE SUN UNTIL ITS SETTING MY NAME IS GREAT AMONG THE NATIONS, <AND IN EVERY PLACE INCENSE IS OFFERED TO MY NAME, EVEN A PURE OBLATION; FOR MY NAME IS GREAT AMONG THE NATIONS, SAYS THE LORD OF HOSTS>. BUT YOU DESECRATE IT WHEN YOU SAY THE TABLE OF THE LORD IS DEFILED, AND ITS SPECIAL FOOD IS TREATED WITH SCORN <LIKE ORDINARY> FOOD. (Deut. 7:7–8): RATHER YOU WERE THE LEAST OF ALL THE PEOPLES. IT WAS BECAUSE OF THE LORD'S LOVE FOR YOU. Because you diminish yourselves for me, I therefore love you, and so it says (in Mal. 1:2–3): I HAVE LOVED YOU, SAYS THE LORD …; BUT I HAVE HATED ESAU…. It also says (in Hos. 14:5 [4]): I WILL HEAL THEIR APOSTASY [AND LOVE THEM VOLUNTARILY]. What is the meaning of AND LOVE THEM VOLUNTARILY? My soul has volunteered to love them, even though they were not worthy; and so it says (in Deut. 7:8): BECAUSE THE LORD LOVES YOU….

Who fulfilled this section (Deuteronomy 20:10-15)? Yehoshua bin Nun. Said Rabbi Shmuel bar Nachman: What did Yehoshua do? He put out an edict everywhere he went to conquer, and this is what was written in it: "Anyone who wants to leave, can leave. Anyone who wants to make peace, make it. Anyone who wants to wage war, wage it." What did the Gergashites do? They turned and left from before them, giving the Holy One, blessed be He, a land as beautiful as His land, called Africa. The Gibeonites made peace him, Yehoushua made peace with them. But the 31 kings came to wage war with him, the Holy One, blessed be He, made them fall into his hand. How do we know? As it says, (Deuteronomy 3:3) "We struck them down, leaving no survivors."...

(Exod. 23:21, cont.:) FOR MY NAME IS WITH HIM. The name of the Holy One is associated with each and every angel.⁵⁸In other words the name of each angel contains the name of the Holy One, e.g., Michael, Rafael, and Gabriel, all of which contain the name, El. Moses said to him: I do not want an angel to go with us.⁵⁹Tanh., Exod. 6:18, reads more clearly: “I do not want an angel to go with us but you.” He said to him: If you <yourself > do not go with us, we are not moving from our place. The Holy One said to him: By your life, even though I will not send an angel before you, I will send the hornet before you, as stated (in Exod. 23:28): I WILL SEND THE HORNET < BEFORE YOU TO DRIVE OUT THE HEVITES, THE CANAANITES, AND THE HITTITES FROM BEFORE YOU>. How did the Amorites die? R. Levi said: He wedded two hornets to each and every one <of them>. Then when each and every hornet poured out its venom right into <an Amorite's> eyes, he died immediately. R. Hiyya bar Abba said: How did they die? A poison entered them, they {became saturated} [contracted diarrhea], and they died in the presence of Israel. R. Berekhyah said: The Holy One bound them before Israel. Then they came and killed them, as stated (in Deut. 3:3): SO THE LORD OUR GOD GAVE OG, KING OF BASHAN, INTO OUR HANDS…. <The Holy One acted> like someone who binds his child's enemy and sets him before his child. In case you say the Amorites were small, the Holy One exalts them (in Amos 2:9): [YET I DESTROYED THE AMORITES BEFORE THEM,] WHOSE STATURE WAS LIKE THE CEDARS IN HEIGHT. And what did I do to them? (Ibid., cont.:) I DESTROYED THEIR FRUIT ABOVE, i.e., their prince; AND THEIR ROOTS BELOW, i.e., the <rest of the> Amorites. The Holy One said: In this world I sent an angel before them, and he destroyed the peoples of the world; but in the world to come, I am sending you Elijah, may his memory be blessed. It is so stated (in Mal. 3:24 [4:5]): LO, I AM SENDING YOU THE PROPHET ELIJAH BEFORE THE COMING OF THE GREAT AND AWESOME DAY OF THE LORD.

R. Abba the son of Kahana maintained: The Holy One, blessed be He, bound them before the Israelites, and they attacked and killed them, as it is said: So the Lord our God delivered into our hand Og (Deut. 3:3). He delivered them into their hands just as a man binds his son’s enemy and places him before his son. You should not maintain that the Amorites were small of stature. Observe what is written about them: Yet destroyed I the Amorite before them, whose height was like the height of the cedars, and he was strong as the oaks; yet I destroyed his fruit from above, and his roots from beneath (Amos 2:9). I destroyed his fruits from above refers to their guardian angel, and his roots from beneath alludes to the Amorites.
