Joshua was of the tribe of Ephraim (Num. 13:8). The western form of his name is "Jesus". In that he was instrumental in leading his people into the Promised Land, there may be more than a few parallels between his namesake, the Son of God, who is leading His followers into another Promised Land -- Heaven.
Joshua was a personal attendant of Moses throughout Israel’s 40 years of wandering in the wilderness. He accompanied Moses to Mount Sinai (Ex. 24:13), and he was one of the Twelve Spies (Num. 13:8,16).
Josephus indicates that he was 85 years old when he succeeded Moses. It is estimated that he spent approximately 6 years subduing the land, and the rest of his life was spent settling and governing the 12 tribes. Correspondingly, his rule over Israel covered about 25 years, until he died at the age of 110.
Joshua was a great warrior and a leader of men, but he never stopped praying to, and trusting, God.
