“And unto Sarah he said, Behold, I have given thy brother a thousand pieces of silver: behold, he is to thee a covering of the eyes, unto all that are with thee, and with all other: thus she was reproved.”
King James Version (KJV)
20:16 Thy brother is to thee a covering of the eyes - Thou must look at no other, nor desire to be looked at by any other. Yoke - fellows must be to each other for a covering of the eyes. The marriage - covenant is a covenant with the eyes, like Job's, #Job 31:1|.
