Genesis 24:65

Therefore she took a vail, &c.— This was done either in conformity to the general custom in ancient times, or it may refer to the particular custom of the nuptial veil, worn by the bride when she was first introduced to her husband.

It is remarkable, that of the ancients the Spartans alone suffered their virgins to appear without veils in public; but when married, they were never suffered to appear without them.
