Acts 2:37-42

37 On hearing this, they were stung in their hearts; and they said to Kefa and the other emissaries, "Brothers, what should we do?"

38 Kefa answered them, "Turn from sin, return to God, and each of you be immersed on the authority of Yeshua the Messiah into forgiveness of your sins, and you will receive the gift of the Ruach HaKodesh!

39 For the promise is for you, for your children, and for those far away - as many as ADONAI our God may call!"

40 He pressed his case with many other arguments and kept pleading with them, "Save yourselves from this perverse generation!"

41 So those who accepted what he said were immersed, and there were added to the group that day about three thousand people.

42 They continued faithfully in the teaching of the emissaries, in fellowship, in breaking bread and in the prayers.
