Sancheirev's Army Burned From Within
When Sancheirev besieges Yerushalayim, Chizkiyahu prays and 185,000 officers die by fire within, their bodies spared as a reward for Shem honoring Noach.
In 3213 (548 BCE), Sancheirev attacked Yehudah and laid siege to Yerushalayim. Chizkiyahu prayed to Hashem. In answer to his tefillos, an astounding miracle occurred; 185,000 of Sancheirev’s officers instantly perished together with their soldiers. The Gemara states that each of these officers led ten soldiers. In what way did they die? The Midrash says they died the same death that Nadav and Avihu did: fire came down from the heavens and burned their insides while leaving their bodies intact. Why were the bodies of the soldiers spared disgrace? It was a reward for the mitzvah that Shem performed when he covered his father Noach while Noach was exposed.
