Charles Ellicott Commentary 2 Kings 23:16

"And as Josiah turned himself, he spied the sepulchres that were there in the mount; and he sent, and took the bones out of the sepulchres, and burned them upon the altar, and defiled it, according to the word of Jehovah which the man of God proclaimed, who proclaimed these things." — 2 Kings 23:16 (ASV)

Turned himself. —So that he caught sight of the tombs on the hillside opposite—not on the hill where the high place was.

The man of God proclaimed. —Some words appear to have fallen out of the Hebrew text here, for the Septuagint adds, when Jeroboam stood in the feast at the altar. And he returned and lifted up his eyes upon the grave of the man of God. (A transcriber’s eye wandered from one “man of God” to the other.) Josiah returned, when on the point of going away.
