( שָׂרָה , Sarah ) occurs but seldom in the Scriptures ( 1 Kings 11:3;  Lamentations 1:1; elsewhere "lady." (See Sarah) ); but the persons to whom it alludes, the daughters of kings, are frequently mentioned, and often with some reference to the splendor of their apparel. Thus we read of Tamar's "garment of divers colors" ( 2 Samuel 13:18), and the dress of the Egyptian princess, the wife of Solomon, is described as "raiment of needlework," and "clothing of wrought gold" ( Psalms 45:13-14). (See Embroidery).
