Charles Ellicott Commentary 2 Kings 23:18

"And he said, Let him be; let no man move his bones. So they let his bones alone, with the bones of the prophet that came out of Samaria." — 2 Kings 23:18 (ASV)

Let him alone. —Or, Let him rest.

So they let his bones alone. —A different verb. And they suffered his bones to escape, namely, disturbance.

With the bones of the prophet ... —See 1 Kings 13:31–32.

That came out of Samaria. —This simply designates the old prophet who deceived the Judean man of God as a citizen of the Northern Kingdom, which was called Samaria, after its capital.
