Midrash su Deuteronomio 7:20

Our masters have taught: Sihon was as strong as a wall tower.³²See above, Deut. 1:5; M. Pss. 136:11. When he sat on the wall his feet reached to the ground, and there was no creature on earth able to stand against him. So what did the Holy One do? He bound his guardian angel (SRW SL M'LH, rt.: 'LH), cast him down, and deliverered him into the hand of Moses. It is so stated (with reference to the Amorite in Amos 2:9, cont.): I DESTROYED HIS FRUIT ABOVE (MM'L, rt.: 'LH) AND HIS ROOTS BELOW, i.e., his seed. Why? Because the Holy One foresaw his children and his children's children up to the resurrection that not one of them would fear Heaven, he immediately cut off his seed. But how did the Amorites die? Rabbi Levi said: The Holy One prepared two hornets for each and every one of them, as stated (in a literal translation of Deut. 7:20): MOREOVER, THE LORD [YOUR] GOD WILL SEND THE HORNET AMONG THEM. Now the hornet flies and smites one in the midst of his eye. Then immediately his eye drops out and he dies. And this is what David said (in Ps. 44:4 [3]): FOR THEY DID NOT TAKE POSSESSION OF THE LAND WITH THEIR OWN SWORD, NOR DID THEIR MIGHTY ARM DELIVER THEM…. If you had not helped them they would not have overcome them. So for that reason, when Moses saw them, he was afraid of them, until the Holy One said to him: Do not be afraid of them. The sages have said: Sihon and Og were stronger than Pharaoh and his armies; for just as they uttered a song over the fall of Pharaoh and his army, so were they worthy to utter <a song> over Sihon and Og. It is simply that David came and uttered a song over them (in Ps. 136:19–20): SIHON, KING OF THE AMORITES, FOR HIS STEADFAST LOVE ENDURES FOREVER; AND OG, KING OF BASHAN, FOR HIS STEADFAST LOVE ENDURES FOREVER.
