 The Pesikta de-Rav Kahana cited for the proposition that God's fate and Israel's fate are intertwined.According to Bar Kappara, God told Israel that the time of God's redemption (when God would release God's right hand, which was restrained while Israel is in exile) was in Israel's hand, and the time of Israel's redemption was in God's hand.As the time of God's redemption (and action) was in Israel's hand, therefore, Israel should heed the words of "let not your heart grow haughty so that you forget the Lord your God."
