Acts 4:2-3, 7-10, 13-14, 18, 20

being sore troubled because they taught the people, and proclaimed in Jesus the resurrection from the dead. And they laid hands on them, and put them in ward unto the morrow: for it was now eventide.

And when they had set them in the midst, they inquired, By what power, or in what name, have ye done this? Then Peter, filled with the Holy Spirit, said unto them, Ye rulers of the people, and elders, if we this day are examined concerning a good deed done to an impotent man, by what means this man is made whole; be it known unto you all, and to all the people of Israel, that in the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even in him doth this man stand here before you whole.

Now when they beheld the boldness of Peter and John, and had perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus. And seeing the man that was healed standing with them, they could say nothing against it.

And they called them, and charged them not to speak at all nor teach in the name of Jesus.

for we cannot but speak the things which we saw and heard.
