John Gill Bible Commentary

And his servants carried him in a chariot dead from Megiddo,.... They took him out of the chariot in which he was wounded, and put him into another, where he died of his wounds by the way; being mortally wounded, he is said to be dead, or a dead man, see Ch2 35:24. and brought him to Jerusalem; which, according to Bunting (b), was forty four miles from Megiddo: and buried him in his own sepulchre; which either he had provided for himself in his lifetime, or which in common belonged to the kings of Judah, see Ch2 35:24. and the people of the land took Jehoahaz the son of Josiah, and anointed him, and made him king in his father's stead; though he was not the eldest son, Jehoiakim, who was afterwards placed in his room, being two years older, as appears from Kg2 23:31 and this is the reason, as the Jewish commentators in general agree, that he was anointed; which they say was never done to the son of a king, unless there was a competitor, or some objection to, or dispute about, the succession, as in the case of Solomon and others. (b) Travels, &c. p. 188.
