I think that lays it out pretty clearly here.
We have Christ as our example of being faithful; and then we have the man Moses who is also faithful. We can look at both examples. They are wonderful examples. But Moses led the people into the wilderness to bring them into the Promised Land, a type of our journey to the Kingdom of God. And these people heard the gospel, as we see in chapter 4, verses 1 and 2 there. They heard the gospel, but they did not mix it with faith. They did not believe the gospel that was preached to them. They did not believe the truth of what God was doing with them.
And so what did they do? They rebelled, they disobeyed. And God said, Ok, if this is the way you're going to be, you're all going to die in the wilderness. So He destroyed them and they did not enter His rest. Paul tells us, let us take a look at this example and learn something from it. And the thing we need to learn from it is that we have heard the gospel, we have to mix it with faith, that is, we have to take what we have heard, be faithful, and obey God. Do the things that He wants us to do, in fear that we will not make it, so that we will make it. And be diligent about it! Have some zeal!
That is what He wants us to do. Take what we have learned, and what we continue to learn, mix it with faith, that is, trust and confidence in God that He can get you where He needs you to be and where you want to be, which is the Kingdom of God. Trust Him that the instructions that He gives you in the Bible are apt for your situation. What you need to do, how you need to be, what your attitude needs to be, and do it, obey it, follow it.
And you know what that is going to do? That is going to land you in His rest. The Promised Land is yours. God will not destroy you in the wilderness. The Kingdom is open to you. Hear the gospel, add some faith, follow the instructions, enter His rest. Sounds easy, does it not? We know it is not. But that is the formula. Hear, faith, follow, firstfruits. Simple to say; hard to do. But that is the general formula.
The author of Hebrews here (Paul, in my estimation) does a masterful job in summarizing the wilderness experience of the children of Israel - all those who came out of Egypt. He has nothing positive to say about them. Not one word. His description of them - the whole generation - is about rebellion, testing and provoking God, going astray, doing evil, being unbelieving, having hard hearts, being deceitful, sinful, disobedient.
In what is essentially an epitaph on an entire generation of Israelites, Paul concludes that they were denied entrance into the Promised Land because they never believed God and that led to their disobedience. They simply did not take His Word as anything of value. So they did not believe it, did not put any stock into it, and did their own thing.
What we see, the end of it all was, as it says here in the New King James, their corpses fell in the wilderness. This is a particularly effective and picturesque illustration, that their corpses fell in the wilderness.
The King James makes it a little bit more macabre. It says it is their carcasses [that] fell in the wilderness. The Phillips version reads that they left their bones in the desert.
The Amplified Bible reads, whose dead bodies were scattered in the wilderness. The Good News Bible (we are getting a little bit more into paraphrases here) reads, who fell down dead in the desert. And, finally, the Message says that they ended up corpses in the wilderness.
The result of all their sin and their rebellion and their provoking God is that they left their rotting carcasses from one end of the wilderness to the other. Every single one of them died. Paul says, Indeed, was it not all who came out of Egypt, led by Moses? All! Every. Single. One.
I was going to go to Hebrews 3:7-15, which kind of summarizes all of this, that Do not harden your heart as in the rebellion, like those Israelites did. I do want to just read just a little part of it.
Now, because our hearts have been transformed by God's Spirit we do not have to follow that sinful destructive pattern of Israel. And as Peter writes,

Those people who rebelled were not willing to continue steadfastly forward and they paid the price.
