And when they had summoned them, they commanded them not to speak or teach at all in the name of Jesus. But Peter and John answered and said to them, “Whether it is right in the sight of God to give heed to you rather than to God, you be the judge; for we cannot stop speaking what we have seen and heard.” Acts4:18-20
And when they had brought them, they stood them before the Council. and the high priest questioned them, saying, “We gave you strict orders not to continue teaching in this name, and behold, you have filled Jerusalem with your teaching, and intend to bring this man’s blood upon us.” But Peter and the apostles answered, “We must obey God rather than men. The God of our fathers raised up Jesus, whom you had put to death by hanging Him on a cross. He is the one whom God exalted to His right hand as a Prince and a Savior, to grant repentance to Israel, and forgiveness of sins. And we are witnesses of these things; and so is the Holy Spirit, whom God has given to those who obey Him.” Acts5:27-32
