I will not put wrongdoing before my eyes

This can be restated to remove the abstract noun "wrongdoing." The idiom, "put evil before my eyes," means to approve of it. Alternate translation: "I will not approve of anyone doing anything that is wrong in my presence" (See: rc://en/ta/man/translate/figs-abstractnouns and rc://en/ta/man/translate/figs-idiom)

it will not cling to me

David describes "evil" as if it were something unable to cling to him. This means that he would avoid evil things and people doing evil things. Alternate translation: "I will completely avoid evil" (See: rc://en/ta/man/translate/figs-personification)

cling

hold on to something or someone very tightly
