כִּ֤י כַפֵּיכֶם֙ נְגֹאֲל֣וּ בַדָּ֔ם וְאֶצְבְּעוֹתֵיכֶ֖ם בֶּֽעָוֺ֑ן שִׂפְתֽוֹתֵיכֶם֙ דִּבְּרוּ־שֶׁ֔קֶר לְשׁוֹנְכֶ֖ם עַוְלָ֥ה תֶהְגֶּֽה׃
因為你們的手掌被血玷污，你們的手指被罪孽沾染；你們的嘴唇說謊言，你們的舌頭吐出邪惡的話。
Mesillat Yesharim
There are some people whose profession is lying. Namely, those people who go around and make up complete lies in order to increase social conversation or to be considered among the intelligent and knowledgeable. On this type it is written "lying lips are an abomination to G-d" (Mishlei 12:22). And also "your lips speak lies, your tongue mutters perverseness" (Isaiah 59:3). Our sages, of blessed memory, have already pronounced their judgment: "four classes of people do not receive the divine presence" (Sanhedrin 103a, Sota 42a), and one of these is the class of liars.
