Numbers 14:33-38

33Your sons shall be wanderers and shepherds in the wilderness for forty years, and they will suffer for your unfaithfulness (spiritual infidelity), until your corpses are consumed in the wilderness.

34According to the number of days in which you spied out the land [of Canaan], forty days, for each day, you shall bear and suffer a year for your sins and guilt, for forty years, and you shall know My displeasure [the revoking of My promise and My estrangement because of your sin].

35I, the Lord, have spoken. I will most certainly do this to all this evil congregation who are gathered together against Me. In this wilderness they shall be consumed [by war, disease, and plagues], and here they shall die.’ ”

36As for the men whom Moses sent to spy out the land, and who returned and made all the congregation murmur and complain against him by bringing back a bad report concerning the land,

37even those [ten] men who brought back the very bad report of the land died by a plague before the Lord.

38But Joshua the son of Nun and Caleb the son of Jephunneh remained alive out of those men who went to spy out the land.
