The Coat of many colors came from the translation from Martin Luther; the more accurate interpretation would be sleeveless coats. It was the intention of Jacob to make Joseph a ruler and Gods dreams confirmed this to have him rule over his brothers and even his mother and father. The brothers were jealous of their younger brother. This story helps us understand the book of revelation chapter 12. There is a women who has stars over her head which is Israel not the Church. The best commentary you can ever buy on the bible is the bible its self. To interpret the women as the church strains what the church really is. Never does scripture state the church is like a pregnant women. But always as a chaste virgin so right there we already have problems to fit it into the chapter 12 scenarios. When they want to kill Joseph they still mention the dreams which they highly resented. Reuben was the older brother who was responsible for the younger boy. He told them to just throw him into the pit but he would want to save him after. They stripped him of his coat, as they stripped Jesus of the garment he had. Joseph being an ruler in Egypt speaks of Jesus being resurrected and risen with authority at the right hand of God.
