Timeline of Moses’ Life in Three Acts

Moses’ life is divided into three 40-year periods, as described in the Bible (Acts 7:23, 7:30; Deuteronomy 34:7), spanning from his birth in 1526 BC to his death in 1406 BC (based on the early Exodus date of 1446 BC). Below, key events from the slaying of the Egyptian taskmaster onward are organized chronologically under each act.

Act 1: First 40 Years in Egypt (1526–1486 BC)

Born in Egypt under Hebrew enslavement, Moses is adopted by Pharaoh’s daughter, raised as a prince, and educated in Egyptian wisdom (Exodus 2:1-10; Acts 7:21-22). This act ends with his impulsive act of rebellion at age 40.

1486 BC: Slays the Egyptian taskmaster – At age 40, Moses kills an Egyptian mistreating a Hebrew, hiding the body, showing his identification with his people but acting impulsively (Exodus 2:11-12; Acts 7:23-25).

Act 2: 40 Years in Midian – Humbling and Herding Sheep (1486–1446 BC)

After fleeing Egypt, Moses lives in Midian as a fugitive, marries Zipporah, and works as a shepherd for Jethro. This period humbles him and culminates in God’s call at the burning bush (Exodus 2:15–4:17; Acts 7:29-30).

1486 BC: Flees to Midian – After the killing is discovered, Moses escapes to Midian to avoid Pharaoh’s wrath (Exodus 2:13-15; Acts 7:29).

1486–1446 BC: Lives in Midian, herding sheep – Moses marries Zipporah, has children (Gershom and Eliezer), and works as a shepherd for Jethro, a humbling contrast to his princely life (Exodus 2:16-22; Acts 7:29).

1446 BC: Burning Bush encounter – At age 80, God appears to Moses in a burning bush at Mount Horeb/Sinai, commissioning him to lead Israel out of Egypt (Exodus 3:1–4:17; Acts 7:30-34).

1446 BC: Fails to speak for himself; God appoints Aaron – Moses protests he is “slow of speech,” so God appoints Aaron to speak on his behalf to Pharaoh and Israel (Exodus 4:10-16).

Act 3: 40 Years in the Wilderness – Leading Israel, Never Entering the Promised Land (1446–1406 BC)

Moses returns to Egypt, leads the Exodus, and guides Israel through the wilderness for 40 years. His failure at Meribah bars him from the Promised Land, and he dies at 120 (Exodus 5–Deuteronomy 34; Acts 7:36).

1446 BC: Returns to Egypt – Moses, with Aaron, returns to confront Pharaoh and rally the Israelites (Exodus 4:18–6:30).

1446 BC: Ten Plagues on Egypt – God sends plagues (blood, frogs, gnats, flies, livestock death, boils, hail, locusts, darkness, firstborn death) over several months to compel Pharaoh to release Israel (Exodus 7–12).

1446 BC (spring, ~March/April): Passover and Exodus from Egypt – Israelites mark doorposts with lamb’s blood; God passes over them. They depart after ~430 years in Egypt (Exodus 12:1-51).

1446 BC (days after Exodus): Red Sea crossing – God parts the Red Sea for Israel to escape; Pharaoh’s army drowns (Exodus 13:17–15:21).

1446 BC: Early wilderness journeys – Post-Red Sea, Israel travels through the wilderness, facing trials (e.g., bitter water at Marah, manna/quail provision) (Exodus 15:22–17:7).

1446 BC (~3 months after Exodus): Arrival at Mount Sinai and giving of the Law – Israel reaches Sinai in the third month; God gives the Ten Commandments and the Law, establishing the covenant (Exodus 19–24; 19:1).

1446 BC: Golden Calf incident and renewed covenant – Israel worships a calf idol while Moses is on Sinai; he intercedes, and God renews the covenant (Exodus 32–34).

1445–1444 BC: Construction of the Tabernacle – Israel builds the portable sanctuary, completed in the first month of the second year (Exodus 35–40; 40:17).

1445 BC: Census and departure from Sinai – First census taken; Israel leaves Sinai after ~11 months (Numbers 1–10:10; 10:11).

1445 BC: Spies sent to Canaan; 40-year wandering sentence – Twelve spies explore Canaan; Israel’s rebellion leads to a 40-year wandering decree (Numbers 13–14).

1445–1406 BC: Wilderness wanderings – Israel wanders for 40 years, facing rebellions (e.g., Korah’s, Numbers 16), battles, and God’s provision (Numbers 15–21; Deuteronomy 2:7).

1406 BC (40th year): Smiting the rock at Meribah (failing to speak for God) – Moses strikes the rock twice instead of speaking to it, dishonoring God, and is barred from the Promised Land (Numbers 20:1-13).

1406 BC: Battles with kings (Sihon and Og) – Israel defeats Amorite kings en route to the Jordan (Numbers 21:21-35).

1406 BC: Balaam and Balak incident – Moab’s king Balak hires Balaam to curse Israel, but he blesses them (Numbers 22–24).

1406 BC: Second census and final instructions – Census on the plains of Moab; Moses gives farewell speeches (Numbers 25–36; Deuteronomy 1–33).

1406 BC: Moses views the Promised Land and dies – At 120, Moses ascends Mount Nebo, sees Canaan, and dies. God buries him (Deuteronomy 34:1-8).
