A curse that does not harm a person is spoken of as if it were a bird that does not land. Alternate translation: "so an undeserved curse does not land on its mark" (See: [[rc://en/ta/man/translate/figs-simile]])
This can be stated with an active form. Alternate translation: "a curse on a person who does not deserve it" (See: [[rc://en/ta/man/translate/figs-activepassive]])
