He that sanctifieth (ο αγιαζων). Present active articular participle of αγιαζω. Jesus is the sanctifier (Hebrews 9:13; Hebrews 13:12).

They that are sanctified (ο αγιαζομενο). Present passive articular participle of αγιαζω. It is a process here as in Hebrews 10:14, not a single act, though in Hebrews 10:10 the perfect passive indicative presents a completed state.

Of one (εξ ενος). Referring to God as the Father of Jesus and of the "many sons" above (verse Hebrews 2:10) and in harmony with verse Hebrews 2:14 below. Even before the incarnation Jesus had a kinship with men though we are not sons in the full sense that he is.

He is not ashamed (ουκ επαισχυνετα). Present passive indicative of επαισχυνομα, old compound (Romans 1:16). Because of the common Father Jesus is not ashamed to own us as "brothers" (αδελφους), unworthy sons though we be.
