Hebrews 5:4
No-one takes this honor upon himself; he must be called by God,
just as Aaron was. (5)
So Christ also did not take upon himself the glory of
becoming a high priest. But God said to him, ‘You are my Son;
today I have become your Father.’
(6)
And he says in another place, ‘You are a priest for ever, in
the order of Melchizedek.’
