Blue - תכלת techeleth, generally supposed to mean an azure or sky color; rendered by the Septuagint ὑακινθον, and by the Vulgate hyacinthum, a sky-blue or deep violet.
Purple - ארגמן argaman, a very precious color, extracted from the purpura or murex, a species of shell-fish, from which it is supposed the famous Tyrian purple came, so costly, and so much celebrated in antiquity. See this largely described, and the manner of dyeing it, in Pliny, Hist. Nat., lib. ix., c. 60-65, edit. Bipont.
Scarlet - תולעת tolaath, signifies a worm, of which this colouring matter was made; and, joined with שני shani, which signifies to repeat or double, implies that to strike this color the wool or cloth was twice dipped: hence the Vulgate renders the original coccum bis tinctum, “scarlet twice dyed;” and to this Horace refers, Odar., lib. ii., od. 16, v. 35:
- Te Bis Afro Murice
Tinctae Vestiunt Lanae -
“Thy robes the twice dyed purple stains.”
It is the same color which the Arabs call al kermez, whence the French cramoisi, and the English crimson. On this subject much may be seen in Bochart, Calmet, and Scheuchzer.
Fine linen - שש shesh; whether this means linen, cotton, or silk, is not agreed on among interpreters. Because שש shesh signifies six, the rabbins suppose that it always signifies the fine linen of Egypt, in which six folds constituted one thread; and that when a single fold was meant, בד bad is the term used. See Clarke’s note on Gen 41:42.
Goats’ hair - עזים izzim, goats, but used here elliptically for goats’ hair. In different parts of Asia Minor, Syria, Cilicia, and Phrygia, the goats have long, fine, and beautiful hair, in some cases almost as fine as silk, which they shear at proper times, and manufacture into garments. From Virgil, Georg. iii., v. 305-311, we learn that goats’ hair manufactured into cloth was nearly of equal value with that formed from wool.
