“Six days later,
Jesus took with him
Peter,
James,
And his brother John.
He led them up
A high mountain,
By themselves.”
Καὶ μεθ’ ἡμέρας ἓξ παραλαμβάνει ὁ Ἰησοῦς τὸν Πέτρον καὶ Ἰάκωβον καὶ Ἰωάνην τὸν ἀδελφὸν αὐτοῦ, καὶ ἀναφέρει αὐτοὺς εἰς ὄρος ὑψηλὸν κατ’ ἰδίαν.
Going to a special mountain can be found in all 3 synoptic gospels, Mark, chapter 9:2, Luke, chapter 9:28, and here in Matthew. Mark and Matthew are exactly the same, word for word, but Luke talked about 8 days and going to pray on the mountain. This activity takes place 6 days (Καὶ μεθ’ ἡμέρας ἓξ) probably after the proclamation of Peter about Jesus being the Christ messiah. Jesus took with him (παραλαμβάνει ὁ Ἰησοῦς) Peter (τὸν Πέτρον), and the 2 sons of Zebedee, James (καὶ Ἰάκωβον) and his brother John (καὶ Ἰωάνην τὸν ἀδελφὸν αὐτοῦ). There was no mention of Peter’s brother Andrew. Jesus brought these 3 disciples to an unnamed high mountain (καὶ ἀναφέρει αὐτοὺς εἰς ὄρος ὑψηλὸν), presumably near the Sea of Galilee, probably Mount Tabor in lower Galilee or Mount Hermon near Caesarea Philippi, much further north. They were by themselves (κατ’ ἰδίαν), not with any of the other apostles or disciples. Going up a high mountain was an attempt to have a special communication with God just as Moses had done in the Old Testament.
