Acts 4:7, 10, 30

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

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.

by stretching forth thine hand to heal; and that signs and wonders may be done by the name of thy holy child Jesus.
