How long were the Israelites in the wilderness before entering the Promised Land?

Scripture indicates Israel spent forty years in the wilderness between the Exodus from Egypt and entry into the Promised Land. The context notes it was a forty-year span to the day, with the Passover in Egypt and later the Passover celebrated when Joshua led them across the Jordan River.

Les explains that God's timing was exact. He notes that Israel was to have a 40-year span from the time they left Egypt until they finally entered the Promised Land, and that it was 40 years to the day. He illustrates this by pointing out that on the Passover night in Egypt, it was the same day and same month of the year, but 40 years later, when they celebrated the Passover with Joshua leading them across the Jordan River. This fits his broader point that all God's timing is right on, never a day late or early.
