וּמְשַׁלְּמֵ֣י רָ֭עָה תַּ֣חַת טוֹבָ֑ה יִ֝שְׂטְנ֗וּנִי תַּ֣חַת רדופי־[רָֽדְפִי־] טֽוֹב׃
They also that repay evil for good are adversaries unto me, because I follow the thing that is good.
Rashi on Psalms
for my pursuit of goodness Because we cleave to the Holy One, blessed be He, and to His commandments.
