Yahweh’s anger burned against Israel, and he made them wander in the wilderness forty years, until the whole generation that had done evil in Yahweh’s sight had perished.
In context
11‘None of the men who came up out of Egypt, from twenty years old and upward, shall see the land I swore to give to Abraham, to Isaac, and to Jacob, because they have not followed me wholeheartedly — 12none but Caleb son of Jephunneh the Kenizzite, and Joshua son of Nun, for they have followed Yahweh wholeheartedly.’ 13Yahweh’s anger burned against Israel, and he made them wander in the wilderness forty years, until the whole generation that had done evil in Yahweh’s sight had perished. 14And now here you are, rising up in your fathers’ place, a brood of sinful men, to add still more to Yahweh’s fierce anger against Israel! 15If you turn away from following him, he will once again leave this whole people in the wilderness, and you will be the ones who destroy them.”
