2 John 9-11 Amplified Version
Anyone who runs on ahead of God and does not abide in the doctrine of Christ, who is not content with what He taught, does not have God; but he who continues to live in the doctrine (teaching) of Christ, does have God, he has both the Father and the Son
If anyone comes to you and does not bring this doctrine, is disloyal to what Jesus Christ taught, do not receive him, do not accept him, do not welcome or admit him into your house or bid him Godspeed or give him encouragement.
For he who wishes him success, who encourage him wishing him Godspeed is a partaker in his evil doings.
Godspeed, this content appears to mean encouragement.
