Charles Ellicott Commentary Hebrews 2:4

"God also bearing witness with them, both by signs and wonders, and by manifold powers, and by gifts of the Holy Spirit, according to his own will." — Hebrews 2:4 (ASV)

God also bearing them witness.—That is, bearing witness with them to the truth they preached. Mark 16:20 is a striking parallel; see also Acts 4:30. The divine attestation was given by miracles and by gifts (literally, distributions, as in the margin; see 1 Corinthians 12:11) of the Holy Spirit. We have here, as in Acts 2:22 and 2 Corinthians 12:12 (see the Notes), the full threefold description of miracles, as signs and wonders and powers; as wonderful works that are performed by divine power, and are thus signs of the divine presence and symbols of a corresponding spiritual work.

The words here used are illustrated especially by 2 Corinthians 12:12, in its reference to miracles as attesting the apostolic preaching. Yet greater works (John 14:12) were performed by the messengers of Christ, because through them the gifts of the Spirit were bestowed. The last words, according to His will, bring us back to the first words of the section (Hebrews 1:1); as it is God who speaks to men in His Son, it is He who works with those who proclaim the word that they have heard, attesting their message by gifts according to His will.
