Hebrews 5:1-6

1 For every chief priest -- out of men taken -- in behalf of men is set in things [pertaining] to God, that he may offer both gifts and sacrifices for sins,
2 able to be gentle to those ignorant and going astray, since himself also is compassed with infirmity;
3 and because of this infirmity he ought, as for the people, so also for himself to offer for sins;
4 and no one to himself doth take the honour, but he who is called by God, as also Aaron:
5 so also the Christ did not glorify himself to become chief priest, but He who spake unto him: `My Son thou art, I to-day have begotten thee;'
6 as also in another [place] He saith, `Thou [art] a priest -- to the age, according to the order of Melchisedek;'
