Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?  Then Peter said unto them, Repent, and be baptized every one in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.  For the promise and children, and to all that are afar off, even as many as the Lord God shall call.  And with many other words did he testify and exhort, saying, Save yourselves from untoward generation.  Then received his word were baptized: and the same day there were added unto them about three thousand souls.  And stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers.
