In the midst of a military campaign, King Josiah is struck by enemy fire and forced to retreat. The primary approach among commentators is that enemy archers targeted the king, hitting him with their arrows.
Following the strike, the king turns to his servants with an urgent plea to be taken away. This request carries a dual purpose. First, there is an immediate need to evacuate him from the active battlefield [ביאור שטיינזלץ]. Second, he needs to be moved out of his current chariot, as the severe injury makes it extremely difficult for him to continue riding in it [מצודת דוד]. The king explains the reason for his sudden retreat to his servants, noting that he has been severely wounded and weakened by the strike.
