¹⁷ “My brothers, I know that what you did to Jesus was done because you did not understand what you were doing. And your leaders did not understand any more than you did. ¹⁸ But God said these things would happen. Through the prophets he said that his Messiah would suffer and die. I have told you how God made this happen. ¹⁹ So you must change your hearts and lives. Come back to God, and he will forgive your sins.
