17:22 Mars’ hill. Same as “Areopagus” in Acts 17:19. This hill near the Acropolis was probably used in Paul’s day by a council that formally evaluated new religious or moral philosophies. “Ares” was the Greek god of war, corresponding to “Mars” in Rome.
17:22 too superstitious. The Athenians were notorious for venerating a great number of gods and goddesses. What may have been religious to the Greeks was superstitious to Paul, since they attributed powers to these personified forces of nature which were only possessed by God.
