Numbers 14:33-38

33And your children shall be wanderers in the wilderness forty years, and shall bear your whoredoms, until your dead bodies be consumed in the wilderness. 34After the number of the days in which ye spied out the land, even forty days, for every day a year, shall ye bear your iniquities, even forty years, and ye shall know my alienation. 35I, Jehovah, have spoken, surely this will I do unto all this evil congregation, that are gathered together against me: in this wilderness they shall be consumed, and there they shall die.

36And the men, whom Moses sent to spy out the land, who returned, and made all the congregation to murmur against him, by bringing up an evil report against the land, 37even those men that did bring up an evil report of the land, died by the plague before Jehovah. 38But Joshua the son of Nun, and Caleb the son of Jephunneh, remained alive of those men that went to spy out the land.
