Numbers 33:37-39

New International Reader's Version

³⁷ They left Kadesh and camped at Mount Hor. It was on the border of Edom. ³⁸ Aaron the priest went up Mount Hor when the Lord commanded him to. That’s where he died. It happened on the first day of the fifth month. It was the 40th year after the Israelites came out of Egypt. ³⁹ Aaron was 123 years old when he died on Mount Hor.
