Numbers 14:30-35

30By no means will you come into the land where I 1swore to settle you, 2except for Caleb the son of Jephunneh and Joshua the son of Nun. 313Your children, however, whom you said would become plunder--I will bring them in, and they will know the land which you have rejected. 324But as for you, your dead bodies will fall in this wilderness. 33Also, your sons will be shepherds in the wilderness for 5forty years, and they will 6suffer for your unfaithfulness, until your bodies perish in the wilderness. 34In accordance with the 7number of days that you spied out the land, forty days, for every day you shall suffer the punishment for your 8guilt a year, that is, forty years, and you will know My opposition. 359I, the Lord, have spoken, I certainly will do this to all this evil congregation who are gathered together against Me. They shall be worn out in this wilderness, and there they shall die.’”
