When the time for Pentecost was fulfilled, they were all in one place together. And suddenly there came from the sky a noise like a strong driving wind, and it filled the entire house in which they were. Then there appeared to them tongues as of fire, which parted and came to rest on each one of them. And they were all filled with the holy Spirit and began to speak in different tongues, as the Spirit enabled them to proclaim.
Peter (said) to them, "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the holy Spirit.
Now when the apostles in Jerusalem heard that Samaria had accepted the word of God, they sent them Peter and John, who went down and prayed for them, that they might receive the holy Spirit, for it had not yet fallen upon any of them; they had only been baptized in the name of the Lord Jesus. Then they laid hands on them and they received the holy Spirit.
When they heard this, they were baptized in the name of the Lord Jesus. And when Paul laid (his) hands on them, the holy Spirit came upon them, and they spoke in tongues and prophesied.
2 Corinthians 1:21-22
But the one who gives us security with you in Christ and who anointed us is God; he has also put his seal upon us and given the Spirit in our hearts as a first installment.
In him you also, who have heard the word of truth, the gospel of your salvation, and have believed in him, were sealed with the promised holy Spirit
