EPHREM THE SYRIAN:
Because Israel, symbolically called “son” since Egypt, had lost its sonship through having worshiped Baal and offered incense to idols, John gave them a name which suited them: race of vipers. Because these had lost that title of sonship, which had been poured over them through grace in the days of Moses, they received from John a name congruent with their deeds. After the Lord went down into the land of the Egyptians and had returned from there, the Evangelist said, “Now the true word spoken by the prophet is accomplished.” He said, “I will call my son out of Egypt.” He also said, “He will be called a Nazarene,” because in Hebrew nezer means a “scepter,” and the prophet calls him a “Nazarene” because he is the Son of the scepter.
