Veil, a cover for the face, or a disguise, from the earliest times has been a sign of chastity and decency in married women. As the sign of chastity they had to cover their faces with veils in the presence of strangers. The putting on of the veil marked the transition from girlhood to womanhood.
Rebekah, the bride, covered herself with a veil on meeting Issac, the groom, (Gen.xxiv.65).
A widow did not wear a veil (Gen. xxxviii.19).
In modern times the bride is covered with a veil in her chamber in the presence of the groom, just before they are led under the canopy. This remaining tradition, resembles the idea that as if the groom is the first whose eyes could celebrate seeing the bride`s face and hair.!
