Numbers 32:6-13

6And Moses said to the children of Gad, and to the children of Reuben, Shall your brethren go to war, and shall ye abide here?

7And why do ye discourage the children of Israel from going over into the land that Jehovah has given them?

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

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

10And Jehovah's anger was kindled the same time, and he swore, saying,

11If the men that came up out of Egypt, from twenty years old and upward, shall see the land that I swore to Abraham, to Isaac, and to Jacob! for they have not wholly followed me;

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

13And Jehovah's anger was kindled against Israel, and he made them wander in the wilderness forty years, until the whole generation was consumed that had done evil in the eyes of Jehovah.
