Carnaim was a strong city in the region of Gilead. It became important after the Babylonian exile. Judas Maccabeus attacked and destroyed Carnaim (1 Maccabees 5:26, 43–44; 2 Maccabees 12:21–23, 26). He also destroyed the temple in the city. This temple was for Atargatis, a Syrian goddess linked to fish.
