The document summarizes events from Numbers 20-21 in which the Israelites wandered in the desert near Kadesh. It describes how Moses and Aaron struck the rock instead of speaking to it to provide water, preventing them from entering the Promised Land. God then sent poisonous snakes to punish the people for complaining again, but provided salvation through a bronze snake on a pole. It also reviews Israel's military victories over Sihon, Og, and other groups as they continued their conquest of Canaan under new leadership after Moses and Aaron.
