Deuteronomy 1:36 (ESV)

36 except Caleb the son of Jephunneh. He shall see it, and to him and to his children I will give the land on which he has trodden, because he has wholly followed the LORD!’

Caleb and his family would be the one exception to the oath. Of that Horeb generation, he would be the only ones granted the privilege of seeing the Promised Land, and receiving the land on which he had walked therein (Hebron), for he followed the Lord wholeheartedly.
