זוהר בראשית — דף רלד ע”א

Jacob's blessing to Joseph is the greatest of all. Joseph received two attributes - strength and kindness. All Israel merited through the merit of Joseph. Every king who sat on the throne of Israel did so in the merit of Joseph. And the Messiah King will also come in the merit of Joseph. Jacob's blessing to Joseph is the last great blessing in Genesis, pointing toward the final redemption.
