“And when they agreed not among themselves, they departed, after that Paul had spoken one word, Well spake the Holy Ghost by Esaias the prophet unto our fathers,”
King James Version (KJV)
28:25 Well spake the Holy Ghost to your fathers - Which is equally applicable to you.
Ac 28:25-28 Well spake the Holy Spirit by Isaiah the prophet. The passage quoted is found in Isa 6:9,10. It is quoted six times: in the Gospels (Mt 13:14,15 Mr 4:12 Lu 8:10 Joh 12:40), here in Acts, and in Romans (Ro 11:7). No other Old Testament passage is so often quoted in the New Testament, and it is always applied to Jewish unbelief. The terrible prediction of the stubborn, willful unbelief of the nation was fulfilled in Isaiah's time, in the time of Christ, in that of his apostles, and eighteen centuries of Jewish history illustrate the same fact to our times. For notes on the passage, see Mt 13:14-17. These are the final "one word" of Paul to the Jews before beginning his work among the Gentiles in Rome.
