Numbers 32:10

8Your fathers did so when I sent them from Kadesh Barnea to see the land.

9For when they went up to 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.

10The LORD’s anger burned in that day, and he swore, saying,

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

12except Caleb the son of Jephunneh the Kenizzite, and Joshua the son of Nun, because they have followed the LORD completely.’
