Numbers 14:33-35

33Also, your sons will be shepherds in the wilderness for 1forty years, and they will 2suffer for your unfaithfulness, until your bodies perish in the wilderness. 34In accordance with the 3number of days that you spied out the land, forty days, for every day you shall suffer the punishment for your 4guilt a year, that is, forty years, and you will know My opposition. 355I, 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.’”
