2 Chronicles 35:24

And his servants therefore took him out of that chariot
Dead, and had him to Jerusalem, and buried him; (See Gill on 2 Kings 23:30),

and all Judah and Jerusalem mourned for Josiah;
he having been so good a king, so tender of them, and such an happy instrument in restoring the true religion, and the service of God; this was the sense of the generality of them, who were sincere in their mourning; but it is not improbable that those who were inclined to idolatry were secretly glad, though they dissembled mourning with the rest.
