Dreadful work was to be made this night in Egypt: all the firstborn of man and beast were this night to be slain, and judgment to be executed upon all the gods of Egypt Their idol-gods. The images made of metal were, probably, melted, those of wood consumed, and those of stone broken to pieces. To this Isaiah 19:1, and Jeremiah 43:13, have been thought to allude. It may also signify, that God destroyed their sacred animals.
