Numbers 14:37 (KJV)

But as for you, your carcases, they shall fall in this wilderness.

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,

But Joshua the son of Nun, and Caleb the son of Jephunneh, which were of the men that went to search the land, lived still.

And Moses told these sayings unto all the children of Israel: and the people mourned greatly.

And they rose up early in the morning, and gat them up into the top of the mountain, saying, Lo, we be here, and will go up unto the place which the LORD hath promised: for we have sinned.

And Moses said, Wherefore now do ye transgress the commandment of the LORD? but it shall not prosper.

Go not up, for the LORD is not among you; that ye be not smitten before your enemies.
