Luke connected the parable of the Good Samaritan with the story of raising the dead son of the widow of Nain.
Luke goes one step further and connects the story of the Good Samaritan with the story of the coronation as king at Bethany. One is the image of “the road down to Jericho.”
Jesus, the narrator, clearly describes the man who fell into the hands of robbers as going down to Jericho, using the expression “a man went down from Jerusalem to Jericho.” The phrase “a priest was going down that road” emphasizes that he was going down to Jericho like the man who fell into the hands of robbers. The narrator, Jesus, says that a Levite came there, saw him, and passed by on the other side. The Levites are also described as going down to Jericho.
Luke uses the word “καταβαίνω” for the expression “going down” in Luke 10:30. And in Luke 19:37, he uses “κατάβασις” for the expression “going down the Mount of Olives”. The noun “κατάβασις” is derived from the verb “καταβαίνω.”
Luke 19:27 says, “He was already nearing the descent of the Mount of Olives,” and this verse creates the image of “the road down to Jericho.”
Therefore, the parable of the Good Samaritan and the story of the coronation of Bethany are linked by the common image of “the road down to Jericho.”
Another is the image of “generously lays down what he has” created through the word “ἐπιβιβάζω.”
When the Good Samaritan approached the man who had fallen into the hands of robbers and finished administering first aid, his next action was to put him on his beast and take him to the inn and care for him. The narrator, Jesus, deliberately uses the word “ἐπιβιβάζω,” which means “to place upon” to describe the action of putting a half-dead man on his beast. Howard Marshall says, “ἐπιβιβάζω” is Lucan.
The word “ἐπιβιβάζω” used by the narrator, Jesus, in the parable of the Good Samaritan, is used again by Luke to describe the coronation as king at Bethany. This should be seen as Luke’s intended use.
Although Jesus rode from Bethany on a colt and entered Jerusalem as a king, he actually entered Jerusalem as a king to be killed, for he foretold his own death (Luke 9:22). In other words, Jesus’ entry into Jerusalem was the entry of “laying down his life” to save his sheep.
Therefore, in terms of “generously laying down what he has”, we see that the parable of the Good Samaritan and the story of the entry into Jerusalem are linked.
