I have consulted commentaries, sermons and John Gill - nobody comments or explains why the term eyelids is used?
It goes back to the Septuagint. I just don't think it is meaningful in English to talk about eyelids testing people. I think the usage (all the way back to the Septuagint) comes from trying to find a parallel for a word that doesn't really have one in other languages.This thread brought out my inner word nerd. I have nothing definitive to say, but did find that the etymology of "lid" includes the idea of "gate (you've probably read the old ways of speaking such as "eye-gate" and "ear-gate."):
Lid: "movable or removable cover for a pot, etc.," mid-13c., from Old English hlid "covering, opening, gate".
The use of "eyelid" goes back to at least the Wycliffe Bible.
