From David to Destruction
Melachim II 19:35 recounts what is often referred to as “the great smite.” After conquering and wreaking terrible havoc upon most of the cities of Judea, including the second most prominent city of Judea, Lachish, the Assyrians set siege on Yerushalayim.274Chizkiyahu built his famous tunnel to provide water for Jerusalem’s residents during the much-anticipated siege. The wide wall Chizkiyahu built to protect Jerusalem from the siege may be viewed in the Old City of Jerusalem’s Jewish Quarter. This wall is referred to in Yeshayahu 22:9–10 and Nechemiah 3:8. Despite the bleak circumstances, Yeshayahu HaNavi prophesies salvation. Finally, after Chizkiyahu HaMelech’s intense Tefillah, on the night of Pesach, the 185,000 Assyrian soldiers die overnight.275Ashkenazim recall these events in the post-Seder poem, “VaYehi BaChatzi HaLayla,” “and it was in the middle of the night of the night.”
Rambam Introduction to the Mishnah
Or he prevents from killing, like that which Elisha prevented Yehoram from killing the troops of Aram that entered Shomron, like the matter that is known (II Kings 6:22); and like that which Yishaya prevented the bringing of water inside the wall (Isaiah 22:9); and like that which Yirmiyahu prevented Israel from going to the Land of Israel (or it should say “to the land of Egypt”) before the completion of seventy years (Jeremiah 42:15); and similar to this matter.
