In the Revised Version the rendering is “it (i.e., Abimelech’s present of 1,000 pieces of silver to Abraham) is for thee a covering of the eyes.” This has been regarded as an implied advice to Sarah to conform to the custom of married women, and wear a complete veil, covering the eyes as well as the rest of the face.
