Revelation 2:12-17 - The Letter To The Church In Pergamum
12 "To the minister of the Church at Pergamum write as follows: "'This is what He who has the sharp, two-edged sword says. I know where you dwell. 13 Satan's throne is there; and yet you are true to Me, and did not deny your faith in Me, even in the days of Antipas My witness and faithful friend, who was put to death among you, in the place where Satan dwells. 14 Yet I have a few things against you, because you have with you some that cling to the teaching of Balaam, who taught Balak to put a stumbling-block in the way of the descendants of Israel--to eat what had been sacrificed to idols, and commit fornication. 15 So even you have some that cling in the same way to the teaching of the Nicolaitans. 16 Repent, at once; or else I will come to you quickly, and will make war upon them with the sword which is in My mouth.
17 "'Let all who have ears give heed to what the Spirit is saying to the Churches. He who overcomes--to him I will give some of the hidden Manna, and a white stone; and--written upon the stone and known only to him who receives it-- a new name.'
