The name of this book in Hebrew, Greek, and English comes from the principle character in it rather than from the writer. Joshua may or may not have been the writer of this book.
The title is appropriate because "Joshua"means, "Yahweh saves."Joshua is the Hebrew name that translates into Aramaic as Jesus. What Jesus is to God's people in a larger sense Joshua was to the Israelites in a smaller sense. Joshua brought God's people into the realization of many of God's plans and purposes for them. This book is a record of God's deliverance of the Israelites into what He had promised them.
In the English Bible, Joshua is one of the historical books (Genesis through Esther). In the Hebrew Bible, it is in the second of the three main divisions of the Old Testament, namely, the Prophets. The Law and the Writings are the first and third divisions. Joshua is the first book in the first half of the Prophets, the Former Prophets. The Former Prophets section contains four books (Joshua, Judges, Samuel, and Kings) as does the second division, the Latter Prophets (Isaiah, Jeremiah, Ezekiel, and the Twelve [minor prophets]). The fact that the Hebrews included mainly historical books such as Joshua in the Prophets section reveals a basic attitude of God's people. They viewed what God revealed here not primarily as a historical record as much as an authoritative record of selected historical events designed to teach important spiritual lessons. We should recognize Joshua, therefore, not simply as a record of history but as a selective history intended to reveal God's will. In the Prophets section of the Old Testament, God revealed Himself through historical events as well as through the oracles of individual prophets.
"The Book of Joshua, like all other books of the Bible, is primarily a book of theology. Through it God has revealed himself and continues to do so."1
