Jehoshua Oshea denotes a desire of salvation, signifying, Save, we pray thee; but Jehoshua, or Joshua, includes a promise of salvation, He will save. So this was a prophecy of his succession to Moses in the government, and of the success of his arms. Joshua is the same name with Jesus, of whom Joshua was a type. He was the Saviour of God's people from the powers of Canaan, Christ from the powers of hell.
