The Conquest of Canaan A military campaign map showing the conquest of Jericho and other Canaanite cities. This map traces Israel's entry into the Promised Land under Joshua. From the camp at Shittim east of the Jordan, spies are sent to Jericho, the people miraculously cross the Jordan at flood stage near Adam-Zarethan, and they establish a base at Gilgal. From there Joshua conquers Jericho and Ai, purges sin at the Valley of Achor, renews the covenant on Mounts Ebal and Gerizim, and receives the Gibeonites seeking a covenant.
