Blue

Blue in the Topics

Generally associated with purple (Ex 25:4; Ex 26:1, Ex 26:31, Ex 26:36, etc.). It is supposed to have been obtained from a shellfish of the Mediterranean, the Helix ianthina of Linnaeus. The robe of the high priest’s ephod was to be all of this colour (Ex 28:31), also the loops of the curtains (Ex 26:4) and the ribbon of the breastplate (Ex 28:28). Blue cloths were also made for various sacred purposes (Num 4:6, Num 4:7, Num 4:9, Num 4:11, Num 4:12). (See Colour.)
