I have remarked before on Rabbi Sacks’ idea on the connection between a garment (beged) and deception (bagad). When clothing is mentioned in the Torah, it is because it serves to deceive, to hide or otherwise cloak the truth.
Yet there is a curious fact. Amidst the story of Tamar, where clothes are used to mask the truth, we have two instances discussing Yosef’s garments. Yosef’s coat is used to fool Yaakov, and his cloak is later used by Potiphar’s wife as evidence as his perfidy. Yosef is unique in the Torah. He is the only person whose garments serve to deceive others when he is not in them. I wonder why.
