Moses's public role is preserved chiefly in biblical tradition, rather than in a contemporary documentary biography. The books of Exodus through Deuteronomy portray him as the mediator through whom Israel was delivered from Egypt and bound to a covenant with God. The date, scale, and historical setting of these events remain debated, and no independently verified chronology of his career can be reconstructed. The narratives nevertheless became foundational accounts of leadership, liberation, and law.

In Exodus, Moses receives a divine commission while tending Jethro's flock in Midian. The encounter at the burning bush sends him back to Egypt to demand the release of the Israelites. Aaron assists him in speaking to Pharaoh. The account describes repeated refusals, plagues, the Passover, and the departure from Egypt, followed by passage through the sea. These are episodes of the religious narrative; their miraculous elements and detailed sequence should not be presented as externally established historical events.

At Sinai, the tradition identifies Moses as the intermediary between God and the people. The Ten Commandments and other laws define obligations within the covenant, while instructions for the tabernacle establish an ordered setting for worship. The golden calf episode dramatizes a breach of that relationship and Moses's intercession for the community. Through subsequent wilderness stories he confronts complaints, challenges to his authority, and the difficulty of sustaining collective allegiance. Leadership appears as a burden involving negotiation and dependence on divine guidance, rather than as uninterrupted personal command.

Deuteronomy presents Moses addressing Israel before entry into the promised land, restating obligations and recalling the wilderness experience. Joshua is designated to lead the next stage. Moses dies in Moab after viewing the land from Mount Nebo, without entering it himself; the narrative says his grave remained unknown. Jewish tradition associates him with the Torah and honors him as an exceptional prophet, while modern scholarship examines the texts as works with complex histories of composition and transmission. Christianity and Islam also developed major interpretations of his prophetic role. These later traditions demonstrate his enormous religious influence but cannot supply missing contemporary evidence for the events of his life.
