Numbers 32:15

11 ‘Because they did not follow Me wholeheartedly, not one of the men twenty years of age or older who came out of Egypt will see the land that I swore to give Abraham, Isaac, and Jacob—

12 not one except Caleb son of Jephunneh the Kenizzite and Joshua son of Nun—because they did follow the LORD wholeheartedly.’

13 The anger of the LORD burned against Israel, and He made them wander in the wilderness forty years, until the whole generation who had done evil in His sight was gone.

14 Now behold, you, a brood of sinners, have risen up in place of your fathers to further stoke the burning anger of the LORD against Israel.

15 For if you turn away from following Him, He will once again leave this people in the wilderness, and you will be the cause of their destruction.”

16 Then the Gadites and Reubenites approached Moses and said, “We want to build sheepfolds here for our livestock and cities for our little ones.

17 But we will arm ourselves and be ready to go ahead of the Israelites until we have brought them into their place. Meanwhile, our little ones will remain in the fortified cities for protection from the inhabitants of the land.

18 We will not return to our homes until every Israelite has taken possession of his inheritance.

19 Yet we will not have an inheritance with them across the Jordan and beyond, because our inheritance has come to us on the east side of the Jordan.”
