Luke indicated that Jesus said to the lawyer (εἶπεν δὲ αὐτῷ) that he had given the correct right answer (Ὀρθῶς ἀπεκρίθης). Jesus told him to do that (τοῦτο ποίει) and then he would live (καὶ ζήσῃ). Mark, chapter 12:32-33, indicated that this Scribe said to Jesus, rather than the other way around, that Jesus was right. He, in fact, respectfully called Jesus Teacher (Διδάσκαλε). This Scribe agreed that Jesus had spoken according to the truth. God was one, so that there was no other God but him alone. Thus, the Scribe and Jesus were on the same page as regards God and his commandments. Then the Scribe pointed out that these 2 commandments were more important than all the Temple sacrifices. He said that to love God with all your heart, with all your understanding, and with all your strength, as well as to love your neighbor as yourself was much more important than all the various sacrificial burnt offerings. This Scribe recognized the value of love of God and neighbor. Do you love God with your whole being and your neighbor as yourself?
All three synoptic gospels, Mark, chapter 5:17 and Luke, chapter 8:37 and Matthew here, have the people in the Gadarenes area ask Jesus to leave their neighborhood, with slight nuances in each story. The whole town went out to meet Jesus (καὶ ἰδοὺ πᾶσα ἡ πόλις ἐξῆλθεν εἰς ὑπάντησιν τῷ Ἰησοῦ). They then begged him to leave their neighborhood or area (καὶ ἰδόντες αὐτὸν παρεκάλεσαν ὅπως μεταβῇ ἀπὸ τῶν ὁρίων αὐτῶν). Not in my neighborhood, as economics was more important than any miraculous events.
