פִּ֭יךָ שָׁלַ֣חְתָּ בְרָעָ֑ה וּ֝לְשׁוֹנְךָ֗ תַּצְמִ֥יד מִרְמָֽה׃
Tu boca metías en mal, Y tu lengua componía engaño.
Rashi on Psalms
you accustomed your tongue to deceit Heb. תצמיד. You accustom deceit to be with you; to speak evil. תצמיד is ajouter in French, to join, as (Num. 19:15): “a cover (צמיד) bound.”
