“Then someone came
What good deed
Must I do
To have eternal life?’”
Καὶ ἰδοὺ εἷς προσελθὼν αὐτῷ εἶπεν Διδάσκαλε, τί ἀγαθὸν ποιήσω ἵνα σχῶ ζωὴν αἰώνιον;
This incident about the man seeking eternal can be found in Mark, chapter 10:17, and Luke, chapter 18:18, but slightly different. This person, not a ruler as in Luke, came to Jesus (Καὶ ἰδοὺ εἷς προσελθὼν αὐτῷ). He called Jesus a teacher (εἶπεν Διδάσκαλε). He wanted to know what one good deed he could do (τί ἀγαθὸν ποιήσω) to achieve eternal life (ἵνα σχῶ ζωὴν αἰώνιον). This person wanted to know about his own personal eternal salvation, while the normal Jewish attitude would have been to talk about how they could all be saved.
