Joseph is 17. He tends flocks with his brothers and brings a bad report about them to their father (Gen 37:2). Israel — Jacob by his covenant name — loves Joseph above all his sons, the son of his old age, the first son of Rachel whom he loved. He makes him a ketonet passim. The word passim is rare — it appears only here and in 2 Samuel 13:18 for the robe of Tamar, the king's virgin daughter. Some translate it "many colors," some "long sleeves," some "an ornamented tunic." Whatever the design, its meaning was unmistakable: Joseph was set apart.
The brothers saw it. They hated him and could not speak peaceably to him. The Torah does not say the father was unaware. It says he loved one son most, and showed it.
