Let them be only for your own, and not for strangers with you.
All Commentaries on Proverbs 5:17 Go To Proverbs 5
Augustine of Hippo
AD 430
“Let the fountain of your water be your own and let no stranger share with you.” For all who do not love God are strangers, are antichrists. And although they enter the basilicas, they cannot be numbered among the sons of God. That fountain of life does not belong to them. Even an evil person can have baptism; even an evil person can have prophecy. We find that king Saul had prophecy; he was persecuting the holy David and was filled with the Spirit of prophecy and began to prophesy. Even an evil person can receive the sacrament of the body and blood of the Lord, for about such it has been said, “He who eats and drinks unworthily eats and drinks judgment to himself.” Even an evil person can have the name of Christ, that is, even an evil person can be called Christian; and about these it has been said, “They profaned the name of their God.” Therefore, even an evil man can have all these mysteries. But he cannot have love and be evil. This, then, is the peculiar gift; it is the unique fountain. For drinking of this the Spirit of God encourages you; for drinking of himself the Spirit of God encourages you.
