Verse 9 I will make them of the synagogue of Satan; deliver them up to the companionship and power of Satan.--Which say they are Jews, and are not; that is, whose professions of reverence for God are insincere. They say they are Jews, and not Christians, but by refusing to receive Jesus as the Messiah, they show that they are not honest believers in the Scriptures and have not really the spirit of Abraham. "He is not a Jew that is one outwardly," &c. (Romans 2:28,29.)--Worship before thy feet; join themselves humbly and reverently to the church of Christ.
