2 John 1:10 in the King James Version
If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed:
Context
9 Whoever transgresses and doesn’t remain in the teaching of Christ doesn’t have God. He who remains in the teaching has both the Father and the Son.
10 If anyone comes to you and doesn’t bring this teaching, don’t receive him into your house, and don’t welcome him,
11 for he who welcomes him participates in his evil deeds.
