Peter denounced Simon the sorcerer.

Acts 8:18-24

18 Simon saw things that convinced him that God had given the Spirit’s power to people as a result of the apostles placing their hands on them. So he offered to give money to the apostles, 19 saying, “Enable me also to do what you are doing, so that everyone on whom I place/put my hands may receive the Holy Spirit’s power.” 20 But Peter said to him, “May you (sg) and your money go to hell, because you mistakenly think that you can buy from us what God alone gives to people 21 God has not authorized you to have any part of this ministry of giving the Holy Spirit’s power, because he knows that you are not thinking rightly! (OR, because he knows that you are thinking completely wrongly.) 22 So stop thinking wickedly like that, and plead that the Lord, if he is willing, will forgive you for what you wickedly thought/planned to do 23 Turn away from your evil ways, because I perceive that you (sg) are extremely envious of us, and you are a slave of your continual desire to do evil! God will certainly punish you severely!” 24 Then Simon answered, “Pray to the Lord God that he will not do to me what you just said!”
