Strong's Concordance #H203, #H204

On, a Reubenite, was one of several leaders who supported Korah's challenge of Moses' authority over Israel.

The modern name of ancient Egypt's city of On is Heliopolis. The city is the Egyptian hometown of Asenath, the wife given to Joseph by Pharaoh. It is through Asenath that Manasseh and Ephraim are born, the future leading tribes of Israel.

The city of On was also one of the centers of sun worship in Egypt.

On, at just two letters, is one of the shortest names in the entire Bible. Others include Ai (Joshua 7:2), Ar (Numbers 21:15), Ir (1Chronicles 7:12), No (Jeremiah 46:25), So (2Kings 17:4), Ur (Genesis 11:28) and Uz (Genesis 10:23).
