In Tyre, Paul and his companions found some local believers and stayed with them for a week. Some of the believers there prophesied through the Holy Spirit that Paul should not continue on top Jerusalem. Apparently Paul did not heed that warning and they again boarded the ship. The entire congregation, including women and children went to the boat where they all knelt and prayed and said their good-byes. Paul and the companions boarded the ship and the people returned to their homes.
The first stop after leaving Tyre was Ptolemais where they had the opportunity to greet the brothers and sisters there. The next day they went on to Caesarea and stayed at the home of Philip the Evangelist who was also one of the seven who had been chosen in the beginning of Acts to distribute food. Philip had four unmarried daughters and each one of them were gifted with the ability to prophesy.
Several days later another man with the gift of prophesy, named Agabus, came from Judea. He took Paul's belt and bound his own feet and hands with it and declared through prophesy that the owner of that belt would be bound, such as he was, by the Jewish leaders in Jerusalem and be turned over to the Gentiles. When Paul's companions heard that, they begged Paul no to go to Jerusalem.
Paul's response was to ask them why they were all weeping. He told them they were breaking his heart. He declared, "I am ready not only to be jailed at Jerusalem but even die for the sake of the Lord Jesus." When Paul's companions realized they could not change his mind they gave up and said, "The Lord's will be done."
They must have been frustrated, especially having heard so many times that Paul's going to Jerusalem would only bring a terrible time for him. They all loved Paul and wanted him to be safe but had to give in and accept his faith and his mission. After that, they all packed and left for Jerusalem along with some of the believers from Caesarea. The believers from Caesarea took them all to the home of Mnason who was originally from Cyprus and they were all welcomed by the brothers and sisters in Jerusalem.
The following day, Paul and his companions went to meet James and all the elders of Jerusalem. After greeting them, Paul gave them a detailed account of all God had done with the Gentiles through his ministry. They all praised God for all He had done and asked Paul if he knew how many thousands of Jews also now believed and still follow the Law of Moses. That seems to be in line with what Paul said earlier about his beliefs as well.
The believers in Jerusalem also told Paul that some Jewish believers there had been told Paul was teaching Jews to abandon the laws of Moses. They had also been told Paul was teaching others not to circumcise their children and to not follow other Jewish customs. Knowing Paul, they must have known he was a follower of the laws and customs as long as they did not contradict the things of Jesus. They asked Paul what they should do about that issue. They were also aware those people would soon find out Paul was in town and might start trouble.
Paul instructed them to take four of the men with them to the Temple and join them in the purification ceremony. They had completed their vow and the custom was to do this ritual upon completion. They were to pay for the men to have their heads ceremoniously shaved. Once all that was done, the other people would know the rumors were false and that they all obeyed the Jewish laws.
However, he was not asking the Gentile believers to do anything like that for they were not obligated to follow Jewish laws and customs. The Gentile believers were to do as they had been instructed by the Jerusalem Council some time ago. They were to abstain from eating any food that had been offered to idols. They should not consume blood or meat from strangled animals and they should abstain from sexual immorality.
The next day, Paul went to the Temple with the men who had already started the purification ritual and had announced the date their vows would end and when the sacrifices would be offered for each of the men who had completed their vows.
When the normal seven days of purification were nearing completion, some Jews from Asia saw Paul in the Temple and without having any idea what he was doing there, they roused a mob and grabbed him. They yelled to the crowds the same thing the Jerusalem believers said they were saying about Paul's teachings. They shouted Paul had preached to their people everywhere telling them to disobey Jewish laws and spoke against the Temple. They added Paul even defiled the Temple by bringing Gentiles in. They assumed, because they had seen Paul earlier that day with a Gentile from Ephesus named Trophimus, Paul had taken him to the Temple thus defiling it.
When the crowds heard that, they were horrified which led to a great riot. Paul was grabbed and dragged from the Temple and they closed the gates behind hm. While they were trying to kill him, the commander of the Roman regiment heard all Rome was in a riot and ran to where it was taking place. When the crowd saw the commander and his troops coming, they stopped beating Paul.
The Romans arrested Paul and bound him with two chains. He asked the crowd about Paul and asked what he had done. Some of the crowd said some things while others had a different story. The crowd was so confused the commander could not get the truth and ordered Paul be taken to the fortress.
As the soldier got close to the fortress, the crowd was so violent, the soldiers had to raise Paul above their shoulders to get him in safely. All the while, the crowd followed shouting "Kill him, kill him!"
Just as the soldiers were leading Paul inside, Paul asked the commander if he could have a word with him. The commander was surprised Paul could speak Greek. He asked Paul if he was the Egyptian who led a rebellion in the past and if he had taken 4,o00 members of the Assassins out into the desert. Paul said he was not that person but told him he was a Jew and a Roman citizen. He told him he was from Tarsus in Cilicia which was an important city. He also asked the commander if he would allow him to address the crowd. The commander agreed allowing him to stand on the stairs asking the crowd to be quiet.
Soon the crowd became very quiet and Paul spoke to them in their native language, Aramaic.
