Joshua
Joshua opens where Deuteronomy closes: Moses is dead, and his aide must lead Israel across the Jordan into the land promised centuries earlier to Abraham. The book moves from miracle to battle to inheritance. Jericho's walls fall, campaigns sweep south and north, and then the pace slows as the land is carefully divided among the tribes, each boundary a receipt of God's faithfulness. Joshua is honest about incomplete obedience and lurking temptation, and it ends with an old man's challenge at Shechem: choose this day whom you will serve. It is a book about promises kept.
Traditionally Joshua; the book is anonymous and includes material after his death.
