Numbers 14:29-30

29Your dead bodies will fall to the ground in this desert. All the men that Moses counted will die. Those were the men who were 20 years old or older when he counted them. They complained against me and now they will die in this desert.

30None of them will go into the land that I promised to give to you to live in. The only men who will go in are Caleb, the son of Jephunneh, and Joshua, the son of Nun.
