Isaiah 6 [.mp3]

⁶ Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar:

⁷ And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged.

Acts 4 [.mp3]

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.
