Acts 26:7

"unto which promise our twelve tribes, earnestly serving God night and day, hope to attain. And concerning this hope. am accused by the Jews,. king!"Our twelve tribes" This is an expression that indicates that the 10 tribes were not lost. This statement Included Jews in and outside of Palestine. Every now and then someone tries to argue that the United States and Britain are the "lost ten tribes of Israel". "Earnestly serving God night and day" Notice that Paul does not hate his brethren according to the flesh or his heritage, neither does he argue that Jews are not seriously about serving God. Paul knew that their devotion was intense (Romans 10:1), and that they were continually offering prayers and sacrifices. "Hope to attain" At this point in history, most Jews were still looking for the fulfillment of the Messiah. Carefully note that sincere, religious devotion separated from faith in Christ does not save (Romans 10:1). Paul is making the point that what he preaches does not ridicule the Jewish faith, but rather, what he preaches is the fulfillment of what all true Jews claim to be wanting. "And concerning this hope. am accused by the Jews,. king" He is "suggesting that it is an utterly amazing thing that the Jews who have the hope which the Old Testament Scriptures promised should persecute Paul for entertaining the very same hope! So the whole dispute boiled down to. question of evidence whether or not Jesus was the promised Messiah and the fulfillment of Israel's hopes. To that evidence Paul now turns" (Reese p. 876).

So here is the train of thought in these and the following verses: The Jews and. have the same hope. They are still looking for the fulfillment of God's promises and. say the fulfillment has come. The proof that Jesus is the Messiah is His resurrection. The proof of the resurrection is the fact that this Jesus appeared to me. This Jesus commanded me to preach to the Gentiles. The O.T. Scriptures clearly teach. Messiah that would suffer, die, be raised from the dead and send salvation to the Jews as well as the Gentiles (Acts 26:22-23). Thus, the prophets backed up what Paul claimed.
