(18) A garment of divers colours.—The word is used only here and in connection with Joseph (Genesis 37:3; Genesis 37:23; Genesis 37:32), and is supposed to mean a tunic with long sleeves, in distinction from those with short sleeves commonly worn. The fact is mentioned to show that Tamar must have been recognised as a royal virgin by Amnon’s servant, as well as by everyone else.

2 Samuel 13:18. She had a garment of divers colours — Of embroidered work. His servant brought her out, &c. — A high contempt of a king’s daughter. But the servant’s dependance on his master overruled all respect due to her. “Tamar thus treated,” says Delaney, “not parted with as an innocent woman, cruelly injured, but thrust out as a prostitute that had seduced to sin, is the strongest image of innocence, barbarously abused, and insufferably insulted, that history affords us; the greatest injury loaded with the greatest indignities! contumely added to cruelty!”

13:1-20 From henceforward David was followed with one trouble after another. Adultery and murder were David's sins, the like sins among his children were the beginnings of his punishment: he was too indulgent to his children. Thus David might trace the sins of his children to his own misconduct, which must have made the anguish of the chastisement worse. Let no one ever expect good treatment from those who are capable of attempting their seduction; but it is better to suffer the greatest wrong than to commit the least sin.A garment of divers colors - See Genesis 37:3. Some prefer here (and there) "a tunic with sleeves," a tunic reaching to the extremities, i. e. the hands and feet, and worn over the common tunic, in room of a robe. 18. garment of divers colours—As embroidery in ancient times was the occupation or pastime of ladies of the highest rank, the possession of these parti-colored garments was a mark of distinction; they were worn exclusively by young women of royal condition. Since the art of manufacturing cloth stuffs has made so great progress, dresses of this variegated description are now more common in the East. Of divers colours; of embroidered work. Compare Genesis 37:3.

And she had a garment of divers colours upon her,.... Of embroidered work, which made her the more observable, and her shame the more manifest. Whether this was interwoven with threads of various colours, or embroidered with figures of flowers, animals, &c. and wrought with the needle, or was painted with different colours, or made up of pieces of various colours, is not certain. See Gill on Genesis 37:3; but according to Braunius (c) it was neither, and so the coat of Joseph, but was a garment with sleeves, reaching down to the ankles, and pieced at the borders with fringe; and, indeed, garments of flowers and various colours were such as in other nations, as in Athens, harlots wore (d) and not virgins, as follows:

for with such robes were the king's daughters that were virgins apparelled; which they wore to distinguish them both from common people, and from married persons of the same quality:

then the servants brought her out, and bolted the door after her; laid hold on her, and brought her out by main force; thrust her out of doors, and turned the key upon her.

(c) De Vest. Sacerdot. Heb. l. 1. c. 17. sect. 21. (d) Suidas in voce

And she had a garment of {h} divers colours upon her: for with such robes were the king's daughters that were virgins apparelled. Then his servant brought her out, and bolted the door after her.

(h) For that which was of various colours or pieces, in those days was greatly esteemed, Ge 37:3, Jud 5:30.
