יַ֣עַן הַכְא֤וֹת לֵב־צַדִּיק֙ שֶׁ֔קֶר וַאֲנִ֖י לֹ֣א הִכְאַבְתִּ֑יו וּלְחַזֵּק֙ יְדֵ֣י רָשָׁ֔ע לְבִלְתִּי־שׁ֛וּב מִדַּרְכּ֥וֹ הָרָ֖ע לְהַחֲיֹתֽוֹ׃
Because with lies ye have cowed the heart of the righteous, when I have not grieved him; and strengthened the hands of the wicked, that he should not return from his wicked way, that he be saved alive;
Rashi on Ezekiel
Because you break the heart of the righteous one with falsehood When you divine unfavorably for him, and he is anguished, and his heart is broken.
