Genesis 37:9

The sun. This second dream confirmed the truth of the former. Joseph relates it with simplicity, not suspecting the ill will of his brethren: but his father easily perceives what effect the narration would have, and desires him to be more cautious. He even points out the apparent incoherence of the dream, as Rachel, who seemed intended by the moon, was already dead; unless this dream happened before that event. St. Augustine (q. 123) observes, this was never literally verified in Joseph, but it was in Jesus Christ, whom he prefigured. (Calmet) --- Some think that Bala, the nurse of Joseph, was intended by the moon. (Tirinus)
