כִּ֤י כַפֵּיכֶם֙ נְגֹאֲל֣וּ בַדָּ֔ם וְאֶצְבְּעוֹתֵיכֶ֖ם בֶּֽעָוֺ֑ן שִׂפְתֽוֹתֵיכֶם֙ דִּבְּרוּ־שֶׁ֔קֶר לְשׁוֹנְכֶ֖ם עַוְלָ֥ה תֶהְגֶּֽה׃
For your hands are defiled with blood, And your fingers with iniquity; Your lips have spoken lies, Your tongue muttereth wickedness.
Read halakhic rulings (Jewish law) on Isaiah 59:3: and classical halakhic sources.
