Genesis 37:9

Yet another dream The repetition of the same thing in another shape, might have taught them that it was both certain and very observable. Behold the sun and the moon His father and mother, here signified by the sun and moon, were not represented in the first dream, because, in the event, his brethren only went at first to Egypt, and there did him obeisance, and it was not till afterward that his father went with them.
