He shall break also the images of Beth-shemesh - שמש בית beith shemesh is, literally, the house or temple of the sun; which was worshipped here, and whose images are said to have been of solid gold. These Nebuchadnezzar was to break and carry away; and the houses of the gods - all the temples of Egypt, he was to burn with fire. Beth-shemesh is the same as Heliopolis.
Images - Rather, pillars (compare the Isaiah 19:19 note), obelisks.
Beth-shemesh - Heliopolis, famous for its obelisks.
