Numbers 32:11-13

11‘The men who came out of Egypt, from 20 years old and upward, will not see the land I promised to Abraham, Isaac and Jacob, for they have not followed after Me with a whole heart—

12except Caleb son of Jephunneh the Kenizzite and Joshua son of Nun, for they were wholehearted after Adonai.’

13The anger of Adonai burned against Israel and He caused them to wander in the wilderness 40 years until all the generation doing that evil in Adonai’s sight was gone.
