Numbers 32:6-12

But Moses said to the sons of Gad and the sons of Reuben, “Shall your brothers go to war while you sit here? Now why are you discouraging the hearts of the Israelites from crossing over into the land which the LORD has given them? This is what your fathers did when I sent them from Kadesh-barnea to see the land! For when they went up to the Valley of Eshcol and saw the land, they discouraged the hearts of the Israelites so that they did not go into the land which the LORD had given them. And the LORD’S anger was kindled on that day and He swore an oath, saying, ‘None of the men who came up from Egypt, from twenty years old and upward, shall see the land which I promised to Abraham, to Isaac, and to Jacob, because they have not followed Me completely, except Caleb the son of Jephunneh the Kenizzite and Joshua the son of Nun, for they have followed the LORD completely.’
