Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear.
Therefore being by the right hand of God exalted, х tee (G3588) dexia (G1188)] - not 'to the right hand of God' (as Olshausen, DeWette, Hackett, Webster and Wilkinson, render the words, against good Greek usage), but "by the right hand of God" (as in our version, with the Vulgate, Luther, Calvin, Beza, Meyer, etc.) - that is, by a glorious forth-putting of divine power. This sense suits best with the whole scope of the argument, which was to prove that God had reversed and undone their treatment of Jesus-raising Him whom they killed, and exalting to supreme power and glory Him whom they had brought so low.
And having received of the Father the promise of the Holy Spirit - that is, the promised Spirit,
He hath shed forth this, which (in its effects) ye [now] see and hear. (The "now" is an addition to the genuine text.)
