Acts 4:29-31 (KJV)
29 And now, Lord, behold their threatenings: and grant unto thy servants, that with all boldness they may speak thy word,
30 By stretching forth thine hand to heal; and that signs and wonders may be done by the name of thy holy child Jesus.
31 And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness.
Acts 4:10-12 (KJV)
10 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.
11 This is the stone which was set at nought of you builders, which is become the head of the corner.
12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
