Asaiah is a rare but significant Hebrew name derived from the word 'Asa,' meaning 'doctor' or 'physician.' It originated during the Second Temple period (6th century BCE) and was popular among Babylonian Jews, also mentioned in the Talmud. Notably, Asaiah ben Pharehah served as High Priest during King Hezekiah's reign. Despite its rarity today, Asaiah holds profound meaning and rich historical significance within Jewish culture.
