Revelation 2:12-17

12“And to the angel (divine messenger) of the church in Pergamum write: These are the words of Him who has and wields the sharp two-edged sword [in judgment]:

13‘I know where you dwell, [a place] where Satan sits enthroned. Yet you are holding fast to My name, and you did not deny My faith even in the days of Antipas, My witness, My faithful one, who was killed (martyred) among you, where Satan dwells.

14But I have a few things against you, because you have there some [among you] who are holding to the [corrupt] teaching of Balaam, who taught Balak to put a stumbling block before the sons of Israel, [enticing them] to eat things that had been sacrificed to idols and to commit [acts of sexual] immorality.

15You also have some who in the same way are holding to the teaching of the Nicolaitans.

16Therefore repent [change your inner self—your old way of thinking, your sinful behavior—seek God’s will]; or else I am coming to you quickly, and I will make war and fight against them with the sword of My mouth [in judgment].

17He who has an ear, let him hear and heed what the Spirit says to the churches. To him who overcomes [the world through believing that Jesus is the Son of God], to him I will give [the privilege of eating] some of the hidden manna, and I will give him a white stone with a new name engraved on the stone which no one knows except the one who receives it.’
