NET
5 Do not rely on a friend; do not trust a companion! Even with the one who lies in your arms, do not share secrets!
Darby
5 Believe ye not in a companion, put not confidence in a familiar friend: keep the doors of thy mouth from her that lieth in thy bosom.
KJV
5 Trust ye not in a friend, put ye not confidence in a guide: keep the doors of thy mouth from her that lieth in thy bosom.
