37 ¶ Now when they heard this, they were pricked in their heart, and said vnto Peter, and to the rest of the Apostles, Men and brethren, What shall we doe?
38 Then Peter said vnto them, Repent, and be baptized euery one of you in the Name of Iesus Christ, for the remission of sinnes, and ye shal receiue the gift of the holy Ghost.
39 For the promise is vnto you, and to your children, and to all that are afarre off, euen as many as the Lord our God shall call.
40 And with many other words did hee testifie and exhort, saying, Saue your selues from this vntoward generation.
41 ¶ Then they that gladly receiued his word, were baptized: and the same day there were added vnto them about three thousand soules.
42 And they continued stedfastly in the Apostles doctrine and fellowship, and in breaking of bread, and in praiers.
