“Send some men to explore the land of Canaan, the country I'm giving to the Israelites. Choose one of the leaders from each of the tribes to go and do this.”
and tell them, ‘Pick up twelve stones from the middle of the Jordan, from right where the priests are standing. Then carry them and set them down at the place where you will camp tonight.’”
