“Then a cloud
From the cloud.
‘This is my beloved Son!
Listen to him!’”
καὶ ἐγένετο νεφέλη ἐπισκιάζουσα αὐτοῖς, καὶ ἐγένετο φωνὴ ἐκ τῆς νεφέλης Οὗτός ἐστιν ὁ Υἱός μου ὁ ἀγαπητός, ἀκούετε αὐτοῦ.
This voice from the cloud can be found in all 3 synoptic gospels, Matthew, chapter 16:5, Luke, chapter 9:34-35, and here in Mark, but there are minor differences in all 3 accounts. The wording of the voice from the cloud sounds almost exactly like the voice from heaven in chapter 1:11, after the baptism of Jesus in the Jordan River by John the Baptist. Instead of from heaven there, the voice comes from a cloud here. This voice did not address Jesus personally. However, the idea of a heavenly voice or a voice from a cloud had a very strong tradition in the Jewish writings of the Hebrew Bible, especially among the prophets and Moses. The Baptism of Jesus, like the transfiguration here, has become the starting point for any theological reflection about early Christian Christology. Mark said that a cloud overshadowed them (καὶ ἐγένετο νεφέλη ἐπισκιάζουσα αὐτοῖς). Then there was a voice from the cloud (καὶ ἐγένετο φωνὴ ἐκ τῆς νεφέλης) that said Jesus was his Son, the beloved one (Οὗτός ἐστιν ὁ Υἱός μου ὁ ἀγαπητός). There was nothing about being pleased by him here. However, there is the further admonition to listen to him (ἀκούετε αὐτοῦ). Mark has a clear connection between the Baptism of Jesus and his transfiguration. Both times, the Father as the voice from heaven or the cloud pronounced that Jesus was his beloved Son.
