Numbers 32:8-15

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

9For 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 the Lord had given them.

10And the Lord’s anger was kindled the same time, and he sware, saying,

11Surely 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:1

12Save Caleb the son of Jephunneh the Kenezite, and Joshua the son of Nun: for they have wholly followed the Lord.

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

14And, behold, ye are risen up in your fathers’ stead, an increase of sinful men, to augment yet the fierce anger of the Lord toward Israel.

15For if ye turn away from after him, he will yet again leave them in the wilderness; and ye shall destroy all this people.
