Deuteronomy 1:21-23 NIV
See, the LORD your God has given you the land. Go up and take possession of it as the LORD, the God of your ancestors, told you. Do not be afraid; do not be discouraged.”
Then all of you came to me and said, “Let us send men ahead to spy out the land for us and bring back a report about the route we are to take and the towns we will come to.”
The idea seemed good to me; so I selected twelve of you, one man from each tribe.
