Some Bible study questions for the Book of Joshua include: Who is Joshua, what is his relationship to Moses, and what mission does God anoint Joshua to complete? Another question may ask where Joshua led the Israelites.
Joshua is the son of Nun, a minister of Moses. When Moses dies, God speaks to Joshua. God appoints Joshua leader of the Israelites and makes him responsible for fulfilling the mission originally given to Moses. "Moses my servant is dead; now therefore arise, go over this Jordan, thou, and all this people, unto the land which I give to them, even to the children of Israel," states Joshua 1:2.
Before leading the Israelites across the Jordan River and into the Promised Land, Joshua serves the Israelites as a spy and as Moses' assistant. Moses openly identifies Joshua as his successor in Deuteronomy 31:7, "And Moses called unto Joshua, and said unto him in the sight of all Israel, Be strong and of good courage: for thou must go with this people unto the land which the Lord hath sworn unto their fathers to give them."
God originally intends for Moses to lead Israel into the Promised Land, but an act of unbelief on Moses' part costs him the privilege. "And the Lord spake unto Moses and Aaron, Because ye believed me not, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them," according to Numbers 20:12.
The previous verse, Numbers 20:11, records Moses' act of unbelief for which God shortens his lifespan.
