עֵ֣ד אֱ֭מוּנִים לֹ֣א יְכַזֵּ֑ב וְיָפִ֥יחַ כְּ֝זָבִ֗ים עֵ֣ד שָֽׁקֶר׃
A faithful witness will not lie; But a false witness breatheth forth lies.
Rashi on Proverbs
but he who speaks lies and always speaks lies, is a false witness.
עֵ֣ד אֱ֭מוּנִים לֹ֣א יְכַזֵּ֑ב וְיָפִ֥יחַ כְּ֝זָבִ֗ים עֵ֣ד שָֽׁקֶר׃
A faithful witness will not lie; But a false witness breatheth forth lies.
