This is because God chose him to be a high priest like Melchizedek.
King Melchizedek of Salem was a priest of God Most High. He brought out some bread and wine
The LORD has made a promise that will never be broken: “You will be a priest for ever, just like Melchizedek.”
He had to be one of us, so that he could serve God as our merciful and faithful high priest and sacrifice himself for the forgiveness of our sins.
My friends, God has chosen you to be his holy people. So think about Jesus, the one we call our apostle and high priest!
Much more could be said about this subject. But it is hard to explain, and all of you are slow to understand.
Jesus has gone there ahead of us, and he is our high priest for ever, just like Melchizedek.
