tn Heb “a stranger.” This does not necessarily refer to a non-Israelite, as has been demonstrated before in the book of Proverbs, but these are people outside the familiar and accepted circles. The point is that such a person would be objective in speaking about your abilities and accomplishments.

sn “Mouth” and “lips” are metonymies of cause; they mean “what is said.” People should try to avoid praising themselves. Self praise can easily become a form of pride, even if it begins with trivial things. It does not establish a reputation; reputation comes from what others think about you.

tn “a foreigner”; KJV, ASV, NASB, NRSV “a stranger.”
