Deuteronomy 1:22-23

22Then all of you came to me and you said, ‘Let us send some men into the land first, before we all go in. They can explore the land. Then they can bring a report to us. They can tell us the best way for us to go in there. They can tell us about the towns that we will come to.’

23I thought that this was a good idea. I chose 12 men, one from each of your tribes.
