i'-lid: Eyes and eyelids in Hebrew are sometimes used synonymously, as in the parallelism of Pr 4:25 (compare Pr 6:4; 30:13):
"Let thine eyes look right on,
And let thine eyelids look straight before thee."
(Compare Job 41:18; Ps 11:4; Jer 9:18.) The alluring power of the wanton woman is conceived of as centered in her eyes (Pr 6:25; Isa 3:16): "Neither let her take thee with her eyelids." Painting the eyelids was resorted to to intensify the beauty, antimony (which see) being used for darkening the lashes (2Ki 9:30; Jer 4:30; Eze 23:40).
