Deuteronomy 31:7-8

7Then Moses fetched Joshua. While all the Israelites listened, Moses said this to Joshua: ‘Be strong and very brave! You will go with these people into the land that the Lord promised to give to their ancestors. You will give them the land which will be their new home.

8The Lord himself goes in front of you. He will always be with you, to help you. He will never leave you. So do not be afraid. Be brave!’
