Acts 3:20

And he shall send ... - Acts 1:1 l. Under this economy of things, he shall send Jesus Christ, that is, the Messiah, to teach people; to redeem them; to save them; to judge the world; to gather his people to himself; and to condemn the wicked. Under this economy they were then. This, therefore, was an argument why they should repent and turn to God, that they might escape in the day of judgment.

Which before was preached ... - Who has been proclaimed as the Messiah. The name “Jesus Christ” is equivalent here to “the Messiah.” The Messiah had been proclaimed to the Jews as about to come. In his time was to be the period of refreshing. He had come; and they were under the economy in which the blessings of the Messiah were to be enjoyed. This does not refer to his personal ministry, or to the preaching of the apostles, but to the fact that the Messiah had been a long time announced to them by the prophets as about to come. All the prophets had preached him as the hope of the nation. It may be remarked, however, that there is here a difference in the manuscripts. A large majority of them read προκεχειρισμενον prokecheirismenon, who was designated or appointed, instead of who was preached. This reading is approved by Griesbach, Knapp, Bengel, etc. It was followed in the ancient Syriac, the Arabic, etc., and is undoubtedly the true reading.
