Hebrews 5:4 BBE

²  He is able to have feeling for those who have no knowledge and for those who are wandering from the true way, because he himself is feeble;

³  And being feeble, he has to make sin-offerings for himself as well as for the people.

⁴  And no man who is not given authority by God, as Aaron was, takes this honour for himself.

⁵  In the same way Christ did not take for himself the glory of being made a high priest, but was given it by him who said, You are my Son, this day I have given you being:

⁶  As he says in another place, You are a priest for ever after the order of Melchizedek.
