Revelation 2:14–16
But I have a few things against you, because some of you hold to the teaching of Balaam, who taught Balak to place a stumbling block before the Israelites so they would eat food sacrificed to idols and commit sexual immorality. / In the same way, some of you also hold to the teaching of the Nicolaitans. / Therefore repent! Otherwise I will come to you shortly and wage war against them with the sword of My mouth.
