"Then, as the Lord our God commanded us, we set out from Horeb and went toward the hill country of the Amorites through all that vast and dreadful wilderness that you have seen, and so we reached Kadesh Barnea. Then I said to you, 'You have reached the hill country of the Amorites, which the Lord our God is giving us. 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.'" NIV translation
Moses continues by reminding the people of their travel to Kadesh Barnea where they were ready to enter the promised land. He reminds them that it was a "dreadful wilderness" where nobody would want to stay. He also encourages them to trust God and to not let fear into their lives. We are also reminded that fear is the opposite of faith and should not be a part of our lives as Christians.
"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. They left and went up into the hill country, and came to the Valley of Eshkol and explored it. Taking with them some of the fruit of the land, they brought it down to us and reported, 'It is a good land that the Lord our God is giving us.'" NIV translation
Moses continues his parting words by remembering his second mistake which was sending men to spy out Canaan. This was not of God because He had already told them that the land was good.
Instead of trusting in the Lord and telling the people to trust in God, Moses agreed to sending men to look it over. This lack of faith would open the door to disobedience as we shall see. A part of the job of any good leader is to get the people to grow in their trust in God. When faced with the opportunity, Moses did not seek the will of God but went with what seemed like a good idea.
