Acts 20:21 - Coke's Commentary on the Holy Bible

Testifying both to the Jews, &c.— The word rendered testifying sometimes means to prove a thing by testimony (ch. Acts 2:40 Acts 8:25.); and sometimes, from a conviction ofits truth and importance, to urge it with great earnestness; 1 Timothy 5:21. 2 Timothy 2:14. It is plain that we are to take it in the latter sense in this place, but both are included, Acts 20:24. Repentance toward God, implies our turning to him in sorrow and contrition, as he is infinitely offended by sin; and faith toward our Lord Jesus Christ signifies the making Christ the grand object of our faith and confidence for the pardon of our sins, the sanctification of our souls—in short, as the meritorious cause of every blessing that we can possibly receive for time and eternity.
