Revelation 2 (HCSB)
The Letter to Pergamum
12 “Write to the angel of the church in Pergamum:
“The One who has the sharp, double-edged sword says: 13 I know where you live—where Satan’s throne is! And you are holding on to My name and did not deny your faith in Me, even in the days of Antipas, My faithful witness who was killed among you, where Satan lives. 14 But I have a few things against you. You have some there who hold to the teaching of Balaam, who taught Balak to place a stumbling block in front of the Israelites: to eat meat sacrificed to idols and to commit sexual immorality. 15 In the same way, you also have those who hold to the teaching of the Nicolaitans. 16 Therefore repent! Otherwise, I will come to you quickly and fight against them with the sword of My mouth.
17 “Anyone who has an ear should listen to what the Spirit says to the churches. I will give the victor some of the hidden manna. I will also give him a white stone, and on the stone a new name is inscribed that no one knows except the one who receives it.
