1 Kings 13:31

And it came to pass, after he had buried him, that he spoke to
his sons, saying
He gave them the following charge:

when I am dead, then bury me in the sepulchre wherein the man of God is
buried;
as it was his own, it might be reasonably thought they would bury him in it without such a charge; but, lest they should not, he gives it:

lay my bones beside his bones;
his view in this was, that when Josiah came to burn the bones of the priests, he would spare the bones of this man of God; and so his, lying by them, and mingled with them, would be spared also, and so it proved, ( 2 Kings 23:18 ) .
