2 John 1:10

Εἴ τις ἔρχεται πρὸς ὑμᾶς, καὶ ταύτην τὴν διδαχὴν οὐ φέρει, μὴ λαμβάνετε αὐτὸν εἰς οἰκίαν, καὶ χαίρειν αὐτῷ μὴ λέγετε·

Ei tis erchetai pros ymas, kai taytēn tēn didachēn oy pherei, mē lambanete ayton eis oikian, kai chairein aytō mē legete·

King James Version (KJV)

If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed:

Modern English

If anyone comes to you and does not bring this teaching, do not take them into your house or welcome them.
