What did the son of Jacob Joseph own that made his brothers angry?

Joseph, the son of Jacob, owned a special coat of many colors, which was a gift from his father. This coat symbolized Jacob's favoritism towards Joseph, leading to jealousy and resentment among his brothers. Their anger was further fueled by Joseph's dreams, which suggested that he would one day rule over them. Ultimately, this combination of favoritism and perceived arrogance drove them to plot against him.
