שְֽׂפַת־אֱ֭מֶת תִּכּ֣וֹן לָעַ֑ד וְעַד־אַ֝רְגִּ֗יעָה לְשׁ֣וֹן שָֽׁקֶר׃
El labio de verdad permanecerá para siempre: Mas la lengua de mentira por un momento.
Rashi on Proverbs
A true tongue will be established forever It will be established and will endure.
Rashi on Proverbs
just for a moment In a fleeting moment, it perishes and leaves, for falsehood has no feet.
