Numbers 32:11

8 So did your fathers, when I sent them from Kadesh-barnea to see the land.

9 For when they went up to the valley of Eshcol, and saw the land, they took from the children of Israel the desire to go into the land which the Lord had given them.

10 And at that time the Lord was moved to wrath, and made an oath, saying,

11 Truly, not one of the men of twenty years old and over who came out of Egypt will see the land which I gave by oath to Abraham, Isaac, and Jacob; because they have not been true to me with all their heart;

12 But only Caleb, the son of Jephunneh the Kenizzite, and Joshua, the son of Nun: because they have been true to the Lord.

13 Then the Lord was angry with Israel, and he made them wanderers in the waste land for forty years? till all that generation who had done evil in the eyes of the Lord was dead.

14 And now you have come to take the place of your fathers, another generation of sinners, increasing the wrath of the Lord against Israel.
