Why Israel Wandered 40 Years in the Wilderness

The crisis stemmed from the report of the twelve spies sent to scout Canaan (Numbers 13–14). Ten spies gave a fearful account of fortified cities and powerful inhabitants, causing the people to rebel, demanding a return to Egypt. Caleb and Joshua urged trust in God's promise. The populace's lack of faith led God to decree that the entire adult generation (except Caleb and Joshua) would die in the wilderness over 40 years—a period of testing and purification before entering the Promised Land.
