When they had brought them, they had them stand before the council. The high priest questioned them, saying, "We gave you strict orders not to teach in this name, yet here you have filled Jerusalem with your teaching and you are determined to bring this man's blood on us." But Peter and the apostles answered, "We must obey God rather than any human authority. The God of our ancestors raised up Jesus, whom you had killed by hanging him on a tree. God exalted him at his right hand as Leader and Savior that he might give repentance to Israel and forgiveness of sins. And we are witnesses to these things, and so is the Holy Spirit whom God has given to those who obey him." When they heard this, they were enraged and wanted to kill them. But a Pharisee in he council named Gamaliel, a teacher of the law, respected by all the people, stood up and ordered the men to be put outside for a short time. Then he said to the, "Fellow Israelites, consider carefully what you propose to do to these men. For some time ago Theudas rose up, claiming to be somebody, and a number of men, about four hundred, joined him; but he was killed, and all who followed him were dispersed and disappeared. After him Judas the Galilean rose up at the time of the census and got people to follow him; he also perished, and all who followed him were scattered. So in the present case, I tell you, keep away from these men and let them alone; because if this plan or this undertaking is of human origin, it will fail; but if it is of God, you will not be able to overthrow them - in that case you may even be found fighting against God!"
They were convinced by him, and when they had called in the apostles, they had them flogged. Then they ordered them not to speak in the name of Jesus, and let them go. As they left the council, they rejoiced that they were considered worthy to suffer dishonor for the sake of the name. And every day in the temple and at home they did not cease to proclaim Jesus as the Messiah.
Acts 21:40 - 22:5
When he had given him permission, Paul stood on the steps and motioned to the people for silence; and when there was a great hush, he addressed them in the Hebrew language, saying: "Brothers and fathers, listen to the defense that I now make before you." When they heard him addressing them in Hebrew, they became even more quiet. Then, he said: "I am a Jew, born in Tarsus in Cilicia, but brought up in this city at the feet of Gamaliel, educated strictly according to our ancestral law, being zealous for God, just as all of you are today. I persecuted this Way up to the point of death by binding both men and women and putting them in prison, as the high priest and the whole council of elders can testify about me. From them I also received letters to the brothers in Damascus, and I went there in order to bind those who were there and to bring them back to Jerusalem for punishment . . . ."
The Sages (Rabbi Binyamin Lau)
Nonetheless, it was Rabban Gamliel who said, "Do not accustom yourself to tithing by estimate." Tithing by estimate inevitably produces mistakes. When a person tithed too little produce, the tithes would be valid but the remaining fruit would remain in the category of tevel, and hence prohibited. Tithing too much produce meant that while the fruit is ritually acceptable it contains an element of hullin. Rabban Gamliel presented a solution to the problem of doubt and of mistakes, not by adopting the path of stringency, but rather "acquiring a teacher for yourself."
