There is a difference between Matthew, chapter 4:5 and Luke here, since Luke has this temptation as the last temptation, not the second one. However, the wording is nearly the same, indicating a shared common source. Luke said that the devil took or led Jesus to Jerusalem (Ἤγαγεν δὲ αὐτὸν εἰς Ἱερουσαλὴμ). He placed or set him on the pinnacle of the Temple (καὶ ἔστησεν ἐπὶ τὸ πτερύγιον τοῦ ἱεροῦ). He said to Jesus (καὶ εἶπεν αὐτῷ). If he was the Son of God (Εἰ Υἱὸς εἶ τοῦ Θεοῦ), he could throw or cast himself down from there (βάλε σεαυτὸν ἐντεῦθεν κάτω). This devil took Jesus to the holy city of Jerusalem, where he placed Jesus on the top of the Temple. Once again, the devil said that if Jesus was truly the Son of God, he could throw himself down because God would provide for him.
ἕνεκεν τούτου καταλείψει ἄνθρωπος τὸν πατέρα αὐτοῦ καὶ τὴν μητέρα,
καὶ ἔσονται οἱ δύο εἰς σάρκα μίαν· ὥστε οὐκέτι εἰσὶν δύο ἀλλὰ μία σάρξ.
This saying of Jesus that points to the importance and indissolubility of marriage can also be found in Matthew, chapter 19:4-6. Mark indicates that Jesus used the creation story of Genesis, chapters 1:27 and 2:24, to emphasize his point. He noted that from the beginning of creation (ἀπὸ δὲ ἀρχῆς κτίσεως) God had made humans male and female (ἄρσεν καὶ θῆλυ ἐποίησεν αὐτοὺς). At the pinnacle of creation, God created humans in his image, as both men and women were created equal in God’s image. Jesus continued that a man leaves his father and mother (ἕνεκεν τούτου καταλείψει ἄνθρωπος τὸν πατέρα αὐτοῦ καὶ τὴν μητέρα). Some Orthodox texts have the phrase about being joined to his wife (καὶ προσκολληθήσεται πρὸς τὴν γυναῖκα αὐτοῦ). The two of them then will become one flesh (καὶ ἔσονται οἱ δύο εἰς σάρκα μίαν), so that they are no longer two but one flesh (ὥστε οὐκέτι εἰσὶν δύο ἀλλὰ μία σὰρξ). Obviously, this has become part of many marriage ceremonial rituals.
