Canaan allowed only what adult to enter?

In the biblical context, Canaan allowed only the adult generation that was born in the wilderness to enter the Promised Land. This was due to the disobedience and lack of faith exhibited by the previous generation, which was condemned to wander for 40 years before being denied entry. Specifically, Joshua and Caleb, the two faithful spies, were the only adults from the original exodus allowed to enter Canaan.
