Vayechi - Miracle of Good Livelihood

What is the idea of the 'angel of redemption' in the bracha of Yaakov to his grandsons Menashe and Efraim? What is the concept of 'etzev' and 'itzavon' that are part of the curse of Adam and Chava?

What is the concept of the 'fish' that is part of the blessing to Yosef's children? How do we avoid the 'evil eye' so that we are not affected by others' negativity? How do we find Hashem in our hearts such that all our experiences are rooted in Him?
