“Herod himself
Had sent men
Who arrested John.
They bound him.
He put him
In prison
On account
Of Herodias,
His brother Philip’s wife.
Because Herod
Had married her.”
Αὐτὸς γὰρ ὁ Ἡρῴδης ἀποστείλας ἐκράτησεν τὸν Ἰωάνην καὶ ἔδησεν αὐτὸν ἐν φυλακῇ διὰ Ἡρῳδιάδα τὴν γυναῖκα Φιλίππου τοῦ ἀδελφοῦ αὐτοῦ, ὅτι αὐτὴν ἐγάμησεν·
This mention of Herod seizing John the Baptist can be found in all 3 synoptic gospels, Matthew, chapter 14:3, Luke, 3:19-20, and here. As if this story was not complicated enough, King Herod, the Roman ruler in Galilee, had already seized or arrested John the Baptist. John had been complaining that King Herod Antipas had married Herodias, the wife of his half-brother Herod Boethus or Philip, after King Herod had divorced his first wife. He had sent his first wife back to her father that started a war. Mark said that Herod had sent men (Αὐτὸς γὰρ ὁ Ἡρῴδης ἀποστείλας) to seize or arrest John (ἐκράτησεν τὸν Ἰωάνην). They bound him up and put him in jail (καὶ ἔδησεν αὐτὸν ἐν φυλακῇ). King Herod did this because of his new wife Herodias, who had been the wife of his brother Philip or Herod Boethus (διὰ Ἡρῳδιάδα τὴν γυναῖκα Φιλίππου τοῦ ἀδελφοῦ αὐτοῦ). Then King Herod married Herodias (ὅτι αὐτὴν ἐγάμησεν).
