Commentary for Zechariah 12:11

like the mourning of Hadadrimmon in the Valley of Megiddon Hadadrimmon has no connection to the Valley of Megiddon. These are, rather, two cases of mourning. [The first is] like the mourning of Ahab the son of Omri, who was slain by Hadadrimmon the son of Tabrimmon in Ramoth Gilead, as it is stated (I Kings 22:36): “A cry passed through the camp.” That is the mourning [of Ahab. The second case is] like the mourning of Josiah the son of Amon, who was slain by Pharoah the lame in the Valley of Megiddon, as it is stated (II Chron. 35:25): “And Jeremiah lamented for Josiah, and all the singing men and singing women spoke in their laments, etc.”
