In the bible, how long did Moses spend wandering in the desert after leading the Israelites out of Egypt?

Moses, also known as Moshe Rabbenu, is the most important prophet in Judaism, and an important prophet in Christianity, Islam, the Bahá'í Faith, and a number of other Abrahamic religions. In the biblical narrative he was the leader of the Israelites and lawgiver, to whom the authorship of the first five books of the bible, the Torah, or "acquisition of the Torah from heaven," is attributed.

God sent Moses back to Egypt to demand the release of the Israelites from slavery. Moses said that he could not speak eloquently, so God allowed Aaron, his elder brother, to become his spokesperson. After the Ten Plagues, Moses led the Exodus of the Israelites out of Egypt and across the Red Sea, after which they based themselves at Mount Sinai, where Moses received the Ten Commandments. After 40 years of wandering in the desert, Moses died within sight of the Promised Land on Mount Nebo.
