NET
4 Everyone must be on his guard around his friends. He must not even trust any of his relatives. For every one of them will find some way to cheat him. And all his friends will tell lies about him.
Darby
4 Take ye heed every one of his friend, and confide not in any brother; for every brother only supplanteth, and every friend goeth about with slander.
KJV
4 Take ye heed every one of his neighbour, and trust ye not in any brother: for every brother will utterly supplant, and every neighbour will walk with slanders.
