At excavations in Mesopotamia and Egypt, Romer explores the cultural and religious milieu that shaped some of the Pentateuch's most powerful stories: creation, God's call to Abraham, and the Israelites' exodus.

Archaeological digs at Jericho and elsewhere unearth clues about the rise of Israel as a kingdom, its rivalry with the much-maligned Philistines, and its eventual disintegration and conquest by invaders from the north and west.
