“This is the one
Of whom
The prophet Isaiah
Spoke
When he said.
‘The voice of one crying out
In the wilderness.
Prepare
The way of the Lord!
Make his paths straight!’”
οὗτος γάρ ἐστιν ὁ ῥηθεὶς διὰ Ἠσαΐου τοῦ προφήτου λέγοντος Φωνὴ βοῶντος ἐν τῇ ἐρήμῳ Ἑτοιμάσατε τὴν ὁδὸν Κυρίου, εὐθείας ποιεῖτε τὰς τρίβους αὐτοῦ.
Matthew followed Mark who introduced John as a fulfilment of a prophecy from the Book of Isaiah. However, the text from Mark, chapter 1:2, was a composite of texts from Isaiah, Malachi and Exodus. Matthew, as well as Luke, dropped the first part of these references. However, Luke, chaper 3:4-6, has a more extended citation from Isaiah. Matthew began with the modified quotation from Isaiah, chapter 40:3, while he moved the Malachi and Exodus material to later in the text, where Jesus quoted them. However, it was clear that John the Baptist was the one (οὗτος γάρ ἐστιν ὁ ῥηθεὶς) that Isaiah the prophet was talking about (διὰ Ἠσαΐου τοῦ προφήτου λέγοντος). He was the messenger being sent ahead. He was a voice crying out in the wilderness (Φωνὴ βοῶντος ἐν τῇ ἐρήμῳ). He was to prepare the way for the Lord (Ἑτοιμάσατε τὴν ὁδὸν Κυρίου,). He was going to make the paths straight (εὐθείας ποιεῖτε τὰς τρίβους αὐτοῦ). Deutero-Isaiah originally talked about a voice in the wilderness leading to a new path out of the Exile, in this oracle of Yahweh, just as there had been a path out of the Exodus. In this wilderness or desert, they were to make a straight path, like a highway for God or the Holy Way. However, this would also be a time of upheaval. The valleys would rise as the mountains and hills would fall, so that the uneven and rough places would become level and plain. All the people would then see the glory of God revealed. Clearly, there was a connection between John the Baptist and Isaiah the prophet.
