Numbers 14:38

34 In keeping with the forty days you spied out the land, you shall bear your guilt forty years—a year for each day—and you will experience My alienation.

35 I, the LORD, have spoken, and I will surely do these things to this entire wicked congregation, which has conspired against Me. They will meet their end in the wilderness, and there they will die.”

36 So the men Moses had sent to spy out the land, who had returned and made the whole congregation grumble against him by bringing out a bad report about the land—

37 those men who had brought out the bad report about the land—were struck down by a plague before the LORD.

38 Of those men who had gone to spy out the land, only Joshua son of Nun and Caleb son of Jephunneh remained alive.

39 And when Moses relayed these words to all the Israelites, the people mourned bitterly.

40 Early the next morning they got up and went up toward the ridge of the hill country. “We have indeed sinned,” they said, “but we will go to the place the LORD has promised.”

41 But Moses said, “Why are you transgressing the commandment of the LORD? This will not succeed!

42 Do not go up, lest you be struck down by your enemies, because the LORD is not among you.
