Joshua 1:1

The first word of the book is a conjunction translated "now" or "and." It shows that this book picks up where Deuteronomy ended.

"’Servant of the LORD’ is a title of honor shared by Abraham, David, and the Servant of the Lord in Isaiah. (It is used most frequently of Moses: Exodus 14:31; Numbers 12:7-8; Deuteronomy 34:5; and thirteen times in Joshua; ’my servant’ occurs twice.) The term ’servant’ was used to designate even the highest officials of a king. . . . Only at the end of his life was he [Joshua] honored with the title ’servant of the LORD’ (Joshua 24:29)." [Note: Madvig, p. 255.]

Joshua was from the tribe of Ephraim (Numbers 13:8; 1 Chronicles 7:27).
