Acts 2:38

And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.

And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.

But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women.

And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.

But this is that which was spoken by the prophet Joel; And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams: And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:
