Numbers 33:37-39

New Life Version

³⁷ And they traveled from Kadesh, and stayed at Mount Hor, beside the land of Edom.

³⁸ Then Aaron the religious leader went up to Mount Hor, as the Lord told him. He died there, in the fortieth year after the people of Israel had left the land of Egypt, on the first day of the fifth month. ³⁹ Aaron was 123 years old when he died on Mount Hor.
