Witness to the Religious Establishment and the kings of the earth.
Paul must witness at Jerusalem (to the Religious Establishment) and to the Roman Government (the kings of the earth). The Jews (Synagogue of Satan) conspire under solemn oath to kill Paul (a plot!). Tertullus, hired by and representing the Religious Establishment, acknowledges to the governor the many benefits provided to them by the Roman government which they have enjoyed! Tertullus then falsely accuses Paul of working to help foment a political revolution or insurrection against the government. We note the bond and agreement of cooperation between the Religious Establishment and the world government system. (Does any of this look familiar in our current time?)
Paul speaks to the Roman governor about sin, righteousness, the judgment to come, and faith in Christ Jesus. Felix becomes frightened as he is convicted of his sin. To Agrippa the Jewish king, he boldly and humbly declares what Jesus said, what God has commanded men to do and how prophecy was fulfilled in Jesus.
for as you have solemnly witnessed to My cause at Jerusalem, so you must witness at Rome also.” Acts23:11
