And they arose,.... Before they slew and ate the passover: and took away the altars that were in Jerusalem; which Ahaz had set up in every corner of Jerusalem, to offer sacrifices upon, Ch2 28:24. and all the altars for incense took they away; for as there were some to offer sacrifices on, there were others to burn incense upon, not to the Lord, but to idols, as the Targum adds: and cast them into the brook Kidron; having reduced them to dust and ashes, see Ch2 29:16.
