God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?
Them - rather, 'God, along with the Lord and His eye-witness, (Hebrews 2:3) bearing witness to it;' 'joining in attestation of it.'
Signs and wonders - performed by Christ and His apostles. "Signs" х seemeia (G4592)] are miracles, or other facts regarded as proofs of a divine mission; "wonders" х terata (G5059)] are miracles viewed as prodigies, causing astonishment (Acts 2:22; Acts 2:33); powers х dunameis (G1411)] are miracles viewed as manifestations of superhuman power.
Divers miracles - `varied (miraculous) powers' (2 Corinthians 12:12) granted to the apostles after the ascension.
Gifts ... х merismois (G3311)] - 'distributions.' The Holy Spirit was given to Christ without measure (John 3:34); but to us it is distributed in various measures and operations (Romans 12:3; Romans 12:6, etc.; 1 Corinthians 12:4-11).
According to his own will - God's sovereign will, assigning one gift to one, another to another (Acts 5:32; Ephesians 1:5).
