Luke 17-18 points to the opposition Jesus faced from the Pharisees. Jesus used their erroneous, selfish point of view as a foil for instructing His followers about the characteristics of authentic discipleship. Whether Jesus was arguing with the leaders of Israel or performing messianic signs of the kingdom, Jesus demonstrated His supremacy in the revelatory acts of God. Jesus fulfilled a unique, elevated position in the storyline of Scripture.
(1) In Luke 17:11-19, Jesus healed ten lepers by declaring them clean. Because skin diseases can be highly contagious, in Leviticus 13-14 Moses established laws for how priests would identify and treat conditions that could spread by contact. In Num 5:1-4, Moses reiterated the demand that those with skin diseases should be quarantined so that the contamination would not spread throughout the camp. Once the priest could no longer identify signs of infection in the diseased person, the priest would offer sacrifices on behalf of the one who was ill. Those suffering from skin diseases had to endure social and religious separation during the process of cleansing. Shocking it was then when a group of ten lepers approached Jesus begging for mercy, and Jesus declared them clean and told them to go to the priest in Jerusalem so that they could offer a sacrifice and be restored to the community. One of the ten lepers, a Samaritan, did not make it to the priest, though. Luke reported that this man returned, gave glory to God, and fell at Jesus’ feet, thanking Him (Luke 17:16).
(2) In Luke 17:26-37, Jesus argued that the Pharisees should consider the dullness of those destroyed in the days of Noah and Lot, and be prepared for the day of the Son of Man. God told both Noah (Gen 6:9-22; 2 Pet 2:5) and Lot (Gen 19:14) to announce to their audiences the imminent judgment that the Lord was bringing upon them. But Noah’s contemporaries and Lot’s sons-in-law did not give the warning a second thought. Jesus saw the same attitude in the Pharisees. They thought themselves exempt from even the possibility of condemnation, galaxies removed from the wicked of ancient times. But Jesus knew the Pharisees were as culpable as those who ignored Noah while he built the ark (Matt 24:37-38//Luke 17:26-27) and the residents of Sodom as they went about partying while Lot preached repentance. Jesus warned them to look at historical precedent and understand that their present course of pursuing earthly security would prove faulty in the day of His wrath when some would be taken and others left to destruction (Matt 24:39-41//Mark 13:15//Luke 17:30-35).
(3) In Luke 18:20, Jesus cited from the Ten Commandments to confront the rich young ruler who wanted to justify himself by mere obedience to the law. Previously, Luke reported that an expert in the law approached Jesus asking, “Teacher, what must I do to inherit eternal life?” (Luke 10:25). The lawyer’s question prompted Jesus to tell the Parable of the Good Samaritan, arguing that loving one’s neighbor included loving one’s natural enemies. The rich young ruler approached Jesus with the same question, confessing to Jesus that he had kept the commandments (Matt 19:16-22//Mark 10:17-22//Luke 18:18-23). Jesus did not challenge his assertion but said, “You still lack one thing: sell all that you have and distribute it to the poor, and you will have treasure in heaven. Then come, follow Me” (Luke 18:22). The young man left “extremely sad,” Luke reported, “because he was very rich” (Luke 18:23). According to Jesus, obedience to the Ten Commandments did not equate to salvation (Exod 20:1-17; Deut 5:6-21). Eternal life is for those who trust Jesus’ word and obey Him.
(4) In Luke 18:31, Jesus stated that the Old Testament predicted His suffering and death at the hands of Gentiles, and the fact that He would rise on the third day. In Psalm 22, the psalmist described his sufferings—sufferings that anticipated what Jesus endured in His trial and crucifixion. In Isaiah 53, the prophet detailed the sufferings of God’s servant. In Ps 16:9-11, the psalmist stated his confidence in God to raise him to eternal life. Jesus told His disciples that the events predicted in texts like these would be accomplished in His forthcoming death and resurrection (Matt 20:17-19//Mark 10:32-34//Luke 18:31-34).

Luke 19-20
In Luke 9:51-19:41, the author recorded Jesus’ final trip to Jerusalem. Along the way, Jesus taught His disciples and the crowds about the kingdom of God. Jesus’ use of the Old Testament in Luke 19-20 reinforced His supremacy in the narrative of Israel’s religion.
(1) In Luke 19:9, Jesus justified His mercy toward Zacchaeus based on the fact that Zacchaeus was a son of Abraham. In Gen 12:1-3 and 15:1-6, God promised Abraham that He would give him both land and descendants, blessing all nations through him. In Luke 13:10-17, Jesus healed a crippled woman in a synagogue of Galilee on the Sabbath; He justified His apparent setting aside of Sabbath work restrictions by appealing to the woman’s place in the line of Abraham. Though the Pharisees despised Zacchaeus because he was a chief tax collector and wealthy (Luke 19:2), Jesus consented to Zacchaeus’ offer of hospitality because Zacchaeus was a son of Abraham (Luke 19:9). What marked Zacchaeus as a recipient of the kingdom was not just the fact that he was an Israelite, but also that he repented, giving half of his possessions to the poor and pledging to pay back fourfold those whom he had defrauded (Luke 19:8).
(2) In Luke 19:38, the crowds praised Jesus by lauding Him in light of Ps 118:26. Psalm 118 is a poem of thanksgiving for God’s victorious deliverance. Though the psalmist endured opposition from the nations surrounding Israel, the Lord helped His people. In Jerusalem, the people rejoiced in the one the Lord sent to rescue them saying, “Blessed is he who comes in the name of the LORD” (Ps 118:26). The crowds welcomed Jesus to Jerusalem by singing to Him the song of Psalm 118 (Matt 21:1-9//Mark 11:1-10//Luke 19:28-40). But Jesus’ tears over Jerusalem made clear that the fullness of the kingdom would not arrive until a later time (Luke 19:41-44). Jerusalem, long the center of spiritual life for the children of Abraham (2 Samuel 6; 1 Kings 8-9; 2 Kings 24-25; Nehemiah 1), was now destined to be destroyed.
(3) In Luke 19:46, Jesus cited Isa 56:7 and Jer 7:11 to confront those buying and selling merchandise in the temple, distracting worship. In Isaiah 56, Isaiah announced that when the Messiah arrived, the nations would gather with Israel and worship God in the temple. God’s house would be a house of prayer for the nations (Isa 56:7). In Jeremiah 7, the prophet confronted the people of Judah because when they were away from the temple, they practiced idolatry and exhibited greed. So, because the people were robbers, when they came into the temple, God’s house became a den of thieves (Jer 7:11). When Jesus came near to the temple (Matt 21:12-17//Mark 11:15-18//Luke 19:45-48), He “began to throw out those who were selling, and He said, ‘It is written, My house will be a house of prayer, but you have made it a den of thieves!’” (Luke 19:46).
(4) In Luke 20:17, Jesus cited Ps 118:22 to help His opponents interpret the Parable of the Vineyard Owner. Jesus told the Parable of a Vineyard Owner to describe God’s judgement upon Israel for their rejection of the prophets and their rejection of Himself (Matt 21:33-46//Mark 12:1-12//Luke 20:9-19). When Jesus told the Jewish leadership that God was taking the vineyard from them and giving it to others, they objected, “No!” (Luke 20:16). Indeed, they would even reject Jesus to maintain their clutch on Israel’s religion. But they would fail—as Jesus said via Ps 118:22, “The stone that the builders rejected—this has become the cornerstone” (Luke 20:17).
(5) In Luke 20:28, 37, the Sadducees cited Deut 25:5 and Jesus cited Exod 3:6, 15 to establish their respective views of the resurrection. The Sadducees attempted to cast doubt on Jesus by publicly asking about the resurrection (Matt 22:23-33//Mark 12:18-27//Luke 20:27-40). The Sadducees referenced Moses’ command in Deut 25:5 that a man should raise up children by the wife of his deceased brother so that Israel would grow in population and she would have an heir to support her in her older age. They asked whose wife she would be in the resurrection, her first husband’s wife or a subsequent brother who took her as his wife. Jesus said that in the resurrection, one’s relationship with God—the living God who appeared to Moses as the God of Abraham, Isaac, and Jacob (Exod 3:6, 15)—mattered more than what relationships one had on earth.
(6) In Luke 20:42-43, Jesus cited Ps 110:1 to portray Himself as David’s Lord and David’s Son. After responding to questions from the Jewish leadership, Jesus questioned them concerning the identity of the Messiah (Matt 22:41-46//Mark 12:35-37//Luke 20:41-44). Psalm 110 described the exalted state of Israel’s king, seated at God’s right hand and ruling the nations as both king and priest. Jesus saw in Ps 110:1 a reference to the Lord speaking to the Messiah. Jesus placed Himself in the position of the Messiah and pressed His opponents regarding how the Messiah could be both David’s Lord and David’s Son. The only valid answer was to be found in the One speaking to them.
