As with Edom and Moab, the Israelites asked permission to pass through the territory of King Sihon, but he refused. When Sihon attacked the Israelites at Jahaz, the Israelites defeated him and captured his land. Later, Moses dispatched troops to capture Jazer, and then they turned north and were met by King Og’s forces. They defeated Og’s forces and took control of his land as well.
