Just like with the fig tree, Jesus had hoped to find "fruit", the fruit of true worship of God, at the Temple but it is not the right time for this, and so the Temple, like the fig tree, is cursed. Exegetes often take this as one of Mark's references to the destruction of the Temple by the Romans, and consequently their dating of Mark after this event. The fig tree is again mentioned in Mark 13:28 by Jesus as part of his eschatological discourse, when its leaves will be full and it will be bearing fruit in the summer, as opposed to the current spring. Matthew has roughly the same story but not Luke or John, although Luke 13:6-9 has Jesus relating a "parable", The Parable of the Barren Fig Tree, about a man not finding fruit on a fig tree. Thomas has Jesus talking about thistles not yielding figs in saying 45, which is also found in the Sermon on the Mount in Matthew 7:16. This section of Mark ends with verses which are paralleled in and , which some have seen as a portion or a follow-on of the Lord's Prayer (see also Discourse on ostentation#Prayer): forgive others so that God may forgive you. Jesus then goes back to the Temple a third time and as he walks through the Temple courts the priests, teachers, and elders come up to him and question his authority to do the things that he is doing. They are trying to get him to say that his authority comes from God and can therefore accuse him of blasphemy. Jesus says he will tell them if they answer him one question. "John's baptism — was it from heaven, or from men? Tell me!" (30) The priests are then trapped. Mark implies that they did not believe in John, so that if they answer from heaven people will ask why they did not believe John. If they answer from men, they would be in conflict with the people, who "did" believe in John. They therefore refuse to answer and accordingly so does Jesus. This allows him to make the priests look bad and incompetent and also allows him to imply to the people that his authority is from God without saying it. This is the first time in Mark that the chief priests, members of the Sanhedrin, are presented as Jesus' opponents. His previous conflicts had been with the Pharisees and scribes or teachers of the law. Jesus has several arguments with the Jewish authorities beginning here and lasting through chapter 12 in which they try to trip him up but continually fail.
