Hebrews 9:6-8, 11-12, 23-28

When these things were all in place, the priests regularly entered the first room as they performed their religious duties. But only the high priest ever entered the Most Holy Place, and only once a year. And he always offered blood for his own sins and for the sins the people had committed in ignorance. By these regulations the Holy Spirit revealed that the entrance to the Most Holy Place was not freely open as long as the Tabernacle and the system it represented were still in use.

So Christ has now become the High Priest over all the good things that have come. He has entered that greater, more perfect Tabernacle in heaven, which was not made by human hands and is not part of this created world. With his own blood—not the blood of goats and calves—he entered the Most Holy Place once for all time and secured our redemption forever.

That is why the Tabernacle and everything in it, which were copies of things in heaven, had to be purified by the blood of animals. But the real things in heaven had to be purified with far better sacrifices than the blood of animals. For Christ did not enter into a holy place made with human hands, which was only a copy of the true one in heaven. He entered into heaven itself to appear now before God on our behalf. And he did not enter heaven to offer himself again and again, like the high priest here on earth who enters the Most Holy Place year after year with the blood of an animal. If that had been necessary, Christ would have had to die again and again, ever since the world began. But now, once for all time, he has appeared at the end of the age to remove sin by his own death as a sacrifice. And just as each person is destined to die once and after that comes judgment, so also Christ was offered once for all time as a sacrifice to take away the sins of many people. He will come again, not to deal with our sins, but to bring salvation to all who are eagerly waiting for him.
