Numbers 32:11-13

11He promised, “None of the men that I brought out from Egypt will go into the land. It is the land that I promised to give to Abraham, Isaac and Jacob. But they have not trusted me completely. So any man who is 20 years old or older will not go into this land.

12Caleb, the son of Jephunneh, and Joshua the son of Nun are the only men who will go into the land. They are the only men who trusted me completely.”

13At that time, the Lord was angry with all the Israelites. He caused them to travel in the desert for 40 years. After that, all the men who had turned against him were dead.’
