And it is yet more abundantly evident, since a different priest arises according to the similitude of Melchisedec,

For it is evident that our Lord sprung of the tribe of Judah, of which tribe spake Moses nothing concerning priesthood.

and this -- 'Yet once' -- doth make evident the removal of the things shaken, as of things having been made, that the things not shaken may remain;

The Holy Spirit making this evident - that, not yet, hath been manifested, the way through the Holy place, so long as the first tent hath a standing.

Now faith is the foundation of our hopes of happiness, and the persuasion we have about things not evident to our senses.

Take heed, brethren, that there be not in any one of you a wicked heart of infidelity, [evident] in departure from the living God:

Therefore, it was essential that He had to be made like His brothers (mankind) in every respect, so that He might [by experience] become a merciful and faithful High Priest in things related to God, to make atonement (propitiation) for the people’s sins [thereby wiping away the sin, satisfying divine justice, and providing a way of reconciliation between God and mankind].

It is evident that, when the priest hood is changed, there is of necessity a change also of the law.
