Deuteronomy 1:34

Because all those men which have seen my glory, and my miracles, which I did in Egypt and in the wilderness, and have tempted me now these ten times, and have not hearkened to my voice; Surely they shall not see the land which I sware unto their fathers, neither shall any of them that provoked me see it: But my servant Caleb, because he had another spirit with him, and hath followed me fully, him will I bring into the land whereinto he went; and his seed shall possess it. (Now the Amalekites and the Canaanites dwelt in the valley.) Tomorrow turn you, and get you into the wilderness by the way of the Red sea. And the LORD spake unto Moses and unto Aaron, saying, How long shall I bear with this evil congregation, which murmur against me? I have heard the murmurings of the children of Israel, which they murmur against me. Say unto them, As truly as I live, saith the LORD, as ye have spoken in mine ears, so will I do to you: Your carcasses shall fall in this wilderness; and all that were numbered of you, according to your whole number, from twenty years old and upward which have murmured against me. Doubtless ye shall not come into the land, concerning which I sware to make you dwell therein, save Caleb the son of Jephunneh, and Joshua the son of Nun.

Thus did your fathers, when I sent them from Kadeshbarnea to see the land. For when they went up unto 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. And the LORD's anger was kindled the same time, and he sware, saying, Surely none of the men that came up out of Egypt, from twenty years old and upward, shall see the land which I sware unto Abraham, unto Isaac, and unto Jacob; because they have not wholly followed me: Save Caleb the son of Jephunneh the Kenezite, and Joshua the son of Nun: for they have wholly followed the LORD. And the LORD's anger was kindled against Israel, and he made them wander in the wilderness forty years, until all the generation, that had done evil in the sight of the LORD, was consumed.

And the space in which we came from Kadeshbarnea, until we were come over the brook Zered, was thirty and eight years; until all the generation of the men of war were wasted out from among the host, as the LORD sware unto them.

Unto whom I sware in my wrath that they should not enter into my rest.

Yet also I lifted up my hand unto them in the wilderness, that I would not bring them into the land which I had given them, flowing with milk and honey, which is the glory of all lands;

Harden not your hearts, as in the provocation, in the day of temptation in the wilderness: When your fathers tempted me, proved me, and saw my works forty years. Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways. So I sware in my wrath, They shall not enter into my rest.)
