Deuteronomy 34:7 says Moses was 120 when he died, but his eyes and strength were not feeble. Moses lived to 120—how? How did Moses live to 120 and remain healthy?
Moses’ life spans three 40-year periods. Acts 7:23 says Moses was an Egyptian prince for his first 40 years. After Moses sided with Israel over Egypt, he spent the next 40 years in exile (Acts 7:30). After rescuing Israel from Egypt, Moses lived another 40 years (Acts 7:36). Moses was a ruler for forty years, a shepherd in exile for forty years, and a leader of freed slaves for forty years.
Moses didn’t pass away at 120 from old age. In Moses’ day, the average longevity was far lower than 120. Moses was helped by magic and didn’t age, but God still finished His plan for him. God used Moses to free the Israelites from Egypt, record God’s Law, and lead them to the Promised Land. Moses couldn’t reach the Promised Land with the Israelites because he disobeyed God in Numbers 20:1–12. When the Israelites were ready to enter and take possession of the land, Moses climbed Mount Nebo and surveyed it from an overlook. The Lord then returned him home (Deuteronomy 34:1–7). Moses’ 120 years show that a believer in God is “indestructible” until God’s plan is fulfilled.
