For those priests. — Rather, For they indeed have been made priests without an oath.
By him that said unto him. — Better, by (or, through) Him that saith of Him. The last five words of the verse are absent from the best authorities: they were not needed for this part of the argument, and are therefore omitted from the quotation. All that has been said in chap. 6 (Hebrews 6:13-18) on confirmation by oath must be brought in here (see Notes on Hebrews 6:16-17): the words of the Psalm are really words of promise, and the “more abundant encouragement” is given us by means of the oath that shall never be reversed.
