Targum zu Bamidbar 33:4

And the Mizraee buried those whom the Lord had killed among them, even all the first-born; and upon their idols did the Word of the Lord do judgments; their molten idols were dissolved, their idols of stone were mutilated, their idols of earthenware broken in pieces, their wooden idols turned to ashes, and their cattle gods were slain with death.
