(For those priests were made without an oath; but this with an oath by him that said unto him, The Lord swore and will not change, you are a priest forever after the order of Melchizedek:)
God is not a man, that he should lie; neither the son of man, that he should repent: has he said, and shall he not do it? or has he spoken, and shall he not make it good?
For the law makes men high priests who have weakness; but the word of the oath, which was since the law, makes the Son, who is consecrated forevermore.
