Numbers 32:10

7 And wherefore discourage ye the heart of the children of Israel from going over into the land which Jehovah hath given them?

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

9 For when they went up unto the valley of Eshcol, and saw the land, they discouraged the heart of the children of Israel, that they should not go into the land which Jehovah had given them.

10 And Jehovah`s anger was kindled in that day, and he sware, saying,

11 Surely none of the men that came up out of Egypt, from twenty years old and upward, shall see the land which I sware unto Abraham, unto Isaac, and unto Jacob; because they have not wholly followed me:

12 save Caleb the son of Jephunneh the Kenizzite, and Joshua the son of Nun; because they have wholly followed Jehovah.

13 And Jehovah`s anger was kindled against Israel, and he made them wander to and fro in the wilderness forty years, until all the generation, that had done evil in the sight of Jehovah, was consumed.
