A further note by way of correction. I uncritically accepted a comment on a Christian website that located the fortress Machaerus (built by King Herod the Great) as being in Galilee. In fact, it is over 100 miles south on the eastern side of the Dead Sea.
This and a number of other elements are suggestive that there is a conflation of Herods going on. John the Baptist is baptizing in Judea, gets arrested by Herod the Tetrarch of Galilee to the north/east so Jesus hears this and flees to Galilee?????
Matt 4:12When Jesus heard that John had been imprisoned, He withdrew to Galilee.
Did the Matthean author correctly believe that his source (Mark) identified Herod the Great (King Herod) in Judea not Tetrarch Antipas had JTB arrested and killed?
This would then mean the alteration the present text of Matthew was later redacted at the dancing girl scene to conform with the Josephus version that identifies Herod Antipas as his killer?
It's all very confusing.
