Genesis 24:65

She took a vail, and·covered herself. — Brides are usually taken to the bridegroom enveloped in a vail, which covers the whole body, and is far larger than that ordinarily worn. At the present time the bride-vail is usually red, the ordinary vail blue or white. By wrapping herself in this vail Rebekah notified that she was the bride. After marriage it was seldom worn at this early period, and so both the Egyptians and Abimelech saw Sarah’s beauty.
