One man will build the Temple of the Lord, and the other will receive honor. One man will sit on his throne and rule, and the other will be a priest on his throne. And these two men will work together in peace.’
God is not a human being, and he will not lie. He is not a human, and he does not change his mind. What he says he will do, he does. What he promises, he makes come true.

The law chooses high priests who are people with weaknesses, but the word of God’s oath came later than the law. It made God’s Son to be the high priest, and that Son has been made perfect forever.
