'Gift of the Holy Spirit' in the Bible

And Peter replied, "Every one of you must repent [i.e., change your hearts and lives] and be immersed in the name of Jesus Christ [i.e., by His authority] so that your sins will be forgiven [by God] and then you will receive the gift of the Holy Spirit [to live in your hearts].

And the believers of Jewish descent, who had come with Peter, were amazed [when they saw] that the gift of the Holy Spirit had [now] been poured out on the Gentiles also.
