Charles H. Spurgeon on Psalms 17:8

Does it not appear to thee to be a work of providence, that considering the weakness of the eye, he has protected it with eyelids, as with doors, which whenever there is occasion to use it are opened, and are again closed in sleep? And that it may not receive injury from the winds, he has planted on it eyelashes like a strainer; and over the eyes has disposed the eyebrows like a penthouse, so that the sweat from the head may do no mischief. —Socrates, in Xenophon.
