Revelation 2:14-15

American Standard Version

¹⁴ But I have a few things against thee, because thou hast there some that hold the teaching of Balaam, who taught Balak to cast a stumblingblock before the children of Israel, to eat things sacrificed to idols, and to commit fornication. ¹⁵ So hast thou also some that hold the teaching of the Nicolaitans in like manner.
