but this one became a priest with an oath because of the one who said to him, “The Lord has sworn and will not change his mind, ‘You are a priest forever’ ”
God is not a human being, that he should lie, or a mortal, that he should change his mind. Has he promised, and will he not do it? Has he spoken, and will he not fulfill it?
For the law appoints as high priests humans, who are subject to weakness, but the word of the oath, which came later than the law, appoints a Son who has been made perfect forever.
