The connection between the great high priest and the people of God in Hebrews has proved a central question for many scholars, including Ernst Käsemann. This book examines previous attempts to explain the flow of the argument in Hebrews 3 and 4 and revisits the proposal of J. Rendel Harris, who thought attention to the two Joshuas of the Hebrew Bible was the key to connecting Heb 3:7–4:13 to its frame. It examines Second Temple interpretations of two texts central to the two Joshuas (Numbers 13–14 and Zechariah 3) and concludes with a positive assessment of much of Harris’s proposal.
