Numbers 14:33-37

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

After the number of the days in which ye searched the land, even forty days, each day for a year, shall ye bear your iniquities, even forty years, and ye shall know my breach of promise.

I the LORD have said, I will surely do it unto all this evil congregation, that are gathered together against me: in this wilderness they shall be consumed, and there they shall die.

And the men, which Moses sent to search the land, who returned, and made all the congregation to murmur against him, by bringing up a slander upon the land,

Even those men that did bring up the evil report upon the land, died by the plague before the LORD.
