Acts 2:39

36 Let all the house of Israel therefore know assuredly, that God hath made him both Lord and Christ, this Jesus whom ye crucified.

37 Now when they heard [this,] they were pricked in their heart, and said unto Peter and the rest of the apostles, Brethren, what shall we do?

38 And Peter [said] unto them, Repent ye, and be baptized every one of you in the name of Jesus Christ unto the remission of your sins; and ye shall receive the gift of the Holy Spirit.

39 For to you is the promise, and to your children, and to all that are afar off, [even] as many as the Lord our God shall call unto him.

40 And with many other words he testified, and exhorted them, saying, Save yourselves from this crooked generation.

41 They then that received his word were baptized: and there were added [unto them] in that day about three thousand souls.

42 And they continued stedfastly in the apostles` teaching and fellowship, in the breaking of bread and the prayers.
