And when they heard [all] this, they gave honor to God, then said to Paul, "Brother, you can see how many thousands of Jewish believers [in Christ] there are [everywhere] and all of them are eager to observe the [requirements of the] law of Moses. Now these Jewish Christians have been informed that you are teaching all the Jews living among the Gentiles to give up [following the teaching of] Moses, [even] telling them not to circumcise their children and not to practice the [other] customs [of the Jewish religion]. What do you think will happen when they hear that you have come [here to Jerusalem]? read more.
So, here is what we would like you to do: We have four men who have made a vow [i.e., a special promise to God]. Take these men and observe the ceremony of purification with them, pay their expenses so they can shave their heads [i.e., to signify that they are making a vow] and [then] everyone will know that there is no truth in what people have been told about you, but that you, too, are living properly and observing the law of Moses. But concerning Gentile believers, we wrote [to them] our decision, that they should avoid [eating] things sacrificed to idols, from [drinking] blood, from [eating] what is strangled and from sexual immorality."

Now Herod was very angry with the people of Tyre and Sidon [Note: These were seaport cities not under his jurisdiction]. They came to him as a group, having befriended Blastus, an officer of the king [Herod], and tried to arrange a peaceful relationship [with him] because the country was dependant on him for their food supply. And then, on a particular day, Herod, dressed in his royal robes, delivered a speech [to the people] from his throne. The people began shouting, "His is the voice of a god and not a man."

When Paul realized that part [of the Sanhedrin] were Sadducees and the other part were Pharisees, he lifted up his voice before the Council and said, "Brothers, I am a Pharisee and the son of a Pharisee. And it is concerning our hope that the dead will be raised that I have been brought to trial." When he said this it stirred up a dispute between the Pharisees and Sadducees and the assembly became divided. For the Sadducees believe there is no resurrection, angels or spirits, but the Pharisees accept all of them [to be true]. read more.
A loud commotion developed [in the Council meeting]. Some of the teachers of the law of Moses who belonged to the Pharisee party stood up and argued, saying, "We can find nothing wrong with this man. What if an angel or spirit did speak to him?" And when a serious debate broke out, the commander was afraid that Paul might [virtually] be torn apart by the mob, so he ordered his soldiers to go down [to the Council meeting] and forcibly remove Paul and take him to the battalion headquarters.

Paul wanted him to travel with him [on a preaching mission] so he had him circumcised in order to avoid prejudice by the Jews in that area, for everyone knew that his father was a Greek.
