And the LORD spoke unto Moses and Aaron: "Because ye believed Me not, to sanctify Me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them."

And they rose early in the morning and went forth into the Wilderness of Tekoa; and as they went forth, Jehoshaphat stood and said, "Hear me, O Judah, and ye inhabitants of Jerusalem: Believe in the LORD your God; so shall ye be established. Believe His prophets; so shall ye prosper."

When he is about to fill his belly, God shall cast the fury of His wrath upon him, and shall rain it upon him while he is eating.

And the head of Ephraim is Samaria, and the head of Samaria is Remaliah's son. If ye will not believe, surely ye shall not be established.'"

Thus saith the LORD: "Cursed be the man that trusteth in man and maketh flesh his arm, and whose heart departeth from the LORD.

For he shall be like the heath in the desert, and shall not see when good cometh, but shall inhabit the parched places in the wilderness, in a salt land and not inhabited.

And to whom did He swear that they should not enter into His rest, but to those who believed not?

So we see that they could not enter in because of unbelief.
