Numbers 32:11-12
11 He 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. 12 Caleb, 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.”
32:11Abraham was the first ancestor of the Israelites, and of other nations. He was the father of Isaac and the grandfather of Jacob.
