Joshua 14:6-9

Then the [tribe of the] sons of Judah approached Joshua in Gilgal, and Caleb the son of Jephunneh the Kenizzite said to him, “You know the word which the LORD said to Moses the man of God concerning me and you in Kadesh-barnea. I was forty years old when Moses the servant of the LORD sent me from Kadesh-barnea to scout the land [of Canaan], and I brought a report back to him as it was in my heart. My brothers (fellow spies) who went up with me made the heart of the people melt with fear; but I followed the LORD my God completely. So Moses swore [an oath to me] on that day, saying, ‘Be assured that the land on which your foot has walked will be an inheritance to you and to your children always, because you have followed the LORD my God completely.’ [Deut 1:35, 36]
