The Hidden Amorites and the Ark That Crushed the Twin Hills at Arnon

"Therefore it is said in the Book of the Wars of the LORD." This is the book of And these are the names (Exodus), in which is written the war that the Holy One, blessed be He, made against Egypt, and the war at the Sea, as it is said, "The LORD will fight for you, and you shall hold your peace" (Exodus 14:14) — this is the war of the Sea; "for the LORD fights for them against Egypt" (Exodus 14:25) — this is the war of Egypt. What is written there? Just as the Holy One, blessed be He, did for them at the Red Sea, as it is said, "till Your people pass over, O LORD, till the people pass over whom You have acquired" (Exodus 15:16). "Till they pass the brooks of Arnon" — "till they pass the Jordan." Therefore it is said, "Vahev in Suphah," that which He gave at the Sea, so He did at the brooks of Arnon. And what miracles were done for them at the brooks of Arnon? When the Amorites heard that Israel wished to pass the brooks of Arnon — and there were caves there — the Amorites hid themselves there, and they thought in their hearts: when Israel passes, we will make war with them and slay them. But they did not know that the Ark went with them and lowered the mountains before them. When it arrived there, there were two mountains resembling two breasts, and the Ark brought them together into the caves, and they were all slain. And this is what is written, "and the slope of the brooks" — these are the two mountains "which incline toward the dwelling of Ar, and lean upon the border of Moab." A parable: to what is the matter like? To a maidservant who saw the son of her mistress in danger and went to save him; so was that mountain which had the breasts upon it, and they were upon the land of Israel; and when it saw that Israel were in danger within it, it inclined toward the dwelling of Ar to save them. And who told this to Israel? The Rabbis explain: there were two lepers there, "Vahev in Suphah," and the cloud cast them outside, and they saw the blood of the Amorites that came forth from the caves, and they came and told Israel. And the Rabbis of the Land of Israel explain that the Well went with them and entered those caves and brought forth the dead from there, and therefore it is said, "and from there to Beer" (Numbers 21:16), for there the Well passed; and through it occurred the miracles that the Holy One, blessed be He, did for them, and He made known to them the vengeance He had wrought upon their enemies.
