גּֽוֹלֶה־סּ֭וֹד הוֹלֵ֣ךְ רָכִ֑יל וּלְפֹתֶ֥ה שְׂ֝פָתָ֗יו לֹ֣א תִתְעָרָֽב׃
He that goeth about as a talebearer revealeth secrets; therefore meddle not with him that openeth wide his lips.
Rashi on Proverbs
with one who divulges secrets, one who gossips, or with one who entices with his lips who speaks smoothly to seduce you and entice you.
