Yaakov (Jacob) had 12 sons including Yosef (Joseph). When Yosef sent his brothers back to their father from Mitzrayim (Egypt) he gave them each a change of clothing. He gave his youngest brother Binyomin (Benjamin) a total of five changes of clothing [Bereishis (Genesis) 45:22]. How many sets of clothing did he give to his brothers overall?
12 brothers – 2 brothers (Yosef and Binyamin) = 10 brothers
10 brothers x 1 set of clothing = 10 sets
Binyomin got 5 sets
10 sets + 5 sets = 15 sets
