In Genesis 37:7-8, Joseph tells his brothers a dream of rule and dominion, in which Joseph, standing supreme as ruler, is paid homage by his self-abasing brothers. Of course, they are angry at this, from a younger brother. Leon R. Kass points out, in The Beginning of Wisdom, page 517, the phrase "even more” that describes how much they hate Joseph, is a play on words, using the verb yosef, "to increase or add", the root of Joseph's name. The brothers hated Yosef very much (yosef):
Genesis 37:7-8: For, behold, we were binding sheaves in the field, and, lo, my sheaf arose, and also stood upright; and, behold, your sheaves stood round about, and made obeisance to my sheaf. And his brethren said to him, Shalt thou indeed reign over us? or shalt thou indeed have dominion over us? And they hated him even more for his dreams, and for his words.
Then Joseph has another dream, which he tells his brother, then his father:
Genesis 37:9-10: And he dreamed yet another dream, and told it his brethren, and said, Behold, I have dreamed a dream more; and, behold, the sun and the moon and the eleven stars made obeisance to me. And he told it to his father, and to his brethren: and his father rebuked him, and said unto him, What is this dream that thou hast dreamed? Shall I and thy mother and thy brethren indeed come to bow down ourselves to thee to the earth?
To make sure that the reader understands what this dream means, Genesis has the father interpret it for them. The sun and the moon represent Joseph's father and mother; the eleven stars represent his eleven brothers. The reader will soon see these dreams come true, when Joseph becomes the vizier in Egypt and all Joseph's brothers showed obeisance to him, although the story spares his parents this indignity.
