Joshua, son of Nun, was from the tribe of Ephraim. His name was originally Hosea before it was changed to Joshua. He was the military leader of Israel while Moses was its spiritual leader. He led Israel into the battle against Amalek.
Joshua was one of twelve spies sent by Moses to spy on the land of Canaan. When the spies returned, Joshua and Caleb were the only ones who believed that they could conquer the land. According to a Midrash, Joshua and Caleb were the only spies who could carry back the vine of fruit.
When Moses died, Joshua became the next leader of Israel. G-d said to him, “Be strong, be brave.” He split and crossed the Jordan River. Joshua sent two spies to Jericho to try and find what their weak spots were. He conquered Jericho in a famous battle and divided the land among the tribes.
According to the Tanakh, Joshua died at the age of 110.
Hebrew spelling: יְהוֹשֻׁעַ
Part of Joshua's story is told in the book of Exodus. It is continued in the book of Joshua. The Book of Joshua is the first book in Nevi'im (Prophets) or the sixth in the Tanakh, immediately after the first five books that comprise the Torah.
