Acts 4:12 (KJV)

And when they had set them in the midst, they asked, By what power, or by what name, have ye done this?

Then Peter, filled with the Holy Ghost, said unto them, Ye rulers of the people, and elders of Israel,

If we this day be examined of the good deed done to the impotent man, by what means he is made whole;

Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.

This is the stone which was set at nought of you builders, which is become the head of the corner.

Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus.

And beholding the man which was healed standing with them, they could say nothing against it.

But when they had commanded them to go aside out of the council, they conferred among themselves,

Saying, What shall we do to these men? for that indeed a notable miracle hath been done by them is manifest to all them that dwell in Jerusalem; and we cannot deny it.

But that it spread no further among the people, let us straitly threaten them, that they speak henceforth to no man in this name.
