Revelation 2:14

ἔχεις. A reads ἔχει.

βαλεῖν. A reads βασιλεῖ.

14. κρατοῦντας τὴν διδαχὴν Βαλαάμ. As we should say “who adhere to the practice taught by Balaam, of eating …” It is called doctrine, because it is a thing that was taught. For the fact of Israel being taught such practices, see Numbers 25:1-2 : for Balaam’s responsibility, ibid. Numbers 31:16. That of Balak is not directly mentioned in the Pentateuch, but is naturally inferred, as we find Moab and Midian united throughout the story.
