Charles Ellicott Commentary Hebrews 2:11

"For both he that sanctifieth and they that are sanctified are all of one: for which cause he is not ashamed to call them brethren," — Hebrews 2:11 (ASV)

For both he that sanctifieth . . .—The special meaning of “sanctify” in this Epistle (Hebrews 9:13; Hebrews 10:10; Hebrews 10:14; Hebrews 10:29; Hebrews 13:12) seems to be, bringing into fellowship with God, the Holy One. “They who are sanctified”—literally, are being sanctified (1 Corinthians 1:18)—are those whom the Captain of their salvation, in fulfillment of the Father’s purpose (Hebrews 2:10), is leading to glory. The thoughts of the last verse, therefore, are repeated here, with a change of figure; and again we note the brief reference to a subject that will be prominent in later chapters; see especially Hebrews 13:12.

Are all of one.—Of one Father. This is the connecting link between Hebrews 2:11 and Hebrews 2:10, which speaks of the “many sons” and their Savior. Though His sonship is unique and infinitely exalted, He is not ashamed to own them as brethren.
