Hebrews 2:11

For The next three verses are an illustration of the moral fitness, and therefore of the Divine necessity, that there should be perfect unity and sympathy between the Saviour and the saved.

both he that sanctifieth and they who are sanctified The idea would perhaps be better, though less literally, expressed by "both the sanctifier and the sanctified," for the idea of sanctification is here not so much that of progressive holiness as that of cleansing (Hebrews 13:12). This writer seems to make but little difference between the words "to sanctify" and "to purify," because in the sphere of the Jewish Ceremonial Law, from which his analogies are largely drawn, "sanctification" meant the setting apart for service by various means of purification. See Hebrews 9:13-14; Hebrews 10:10; Hebrews 10:14; Hebrews 13:12, and comp. John 17:17-19; 1 John 1:7.

Or are we to suppose that this application of Messianic Psalms would have come with even greater argumentative force to his Judaising readers?
