Numbers 14:33-35

33And your children shall wander in the wilderness forty years, and bear your whoredoms, until your carcases be wasted in the wilderness.

34After the number of the days in which ye have searched out the land, forty days, each day for a year shall ye bear your iniquities forty years, and ye shall know mine estrangement [from you].

35I Jehovah have spoken; I will surely do it unto all this evil assembly which have gathered together against me! in this wilderness they shall be consumed, and there they shall die.
