Joshua 14:6, 9, 14

Then the people of Judah came to Joshua at Gilgal. And Caleb the son of Jephunneh the Kenizzite said to him, “You know what the LORD said to Moses the man of God in Kadesh-barnea concerning you and me.

And Moses swore on that day, saying, ‘Surely the land on which your foot has trodden shall be an inheritance for you and your children forever, because you have wholly followed the LORD my God.’

Therefore Hebron became the inheritance of Caleb the son of Jephunneh the Kenizzite to this day, because he wholly followed the LORD, the God of Israel.
