Revelation 2:14-15

New Revised Standard Version Catholic Edition

¹⁴ But I have a few things against you: you have some there who hold to the teaching of Balaam, who taught Balak to put a stumbling block before the people of Israel, so that they would eat food sacrificed to idols and practice fornication. ¹⁵ So you also have some who hold to the teaching of the Nicolaitans.
