Luke 3:1 “Now in the fifteenth year of the reign of Tiberius Caesar, Pontius Pilate being governor of Judea, Herod being tetrarch of Galilee, his brother Philip tetrarch of Iturea and the region of Trachonitis, and Lysanias tetrarch of Abilene,”
Tetrarchs ruled the various sections of a region. They thus shared rule of a larger portion.This was a common way rule was handled in this region at the time. Tiberius was the second emperor of Rome.
Heavenly Father, You set up the earthly authorities, and You know all Your plans for this planet. May we never fail to see Your great glory! You are truly worthy of all praise! In the Name of the Lord Jesus Christ I pray and praise You, Amen.
