And the altars that were on the top of the upper chamber of Ahaz, which the kings of Judah had made,.... Which were on the roof of the royal palace; the roofs of houses in Judah being flat, De 21:8 altars might be built upon them; so, in Arabia, altars were built on the tops of houses to offer incense thereon daily to the sun ; as here by Manasseh and Amon very probably, which might be chosen because nearer the heavens; for which reason the Heathens made use of high places to worship in, see Jer 19:13and the altars which Manasseh had made in the two courts of the house of the Lord; 2Ki 21:5did the king beat down; ordered to be demolished:and brake them down from thence, and cast the dust of them into the brook Kidron; that there might be no remains of them to be put to any superstitious use.
