יחזקאל יז:יד מדרש: Midrash Tanchuma Buber

Another interpretation (of Ezek. 17:14): THEN ALL THE TREES OF THE FIELD SHALL KNOW < THAT I THE LORD >. < The verse > speaks about Abraham. (Ibid., cont.:) < THAT I THE LORD > HAVE BROUGHT DOWN THE LOFTY TREE. This is Pharaoh. (Ibid., cont.:) HAVE EXALTED THE LOWLY TREE. This is Abraham. (Ibid., cont.:) HAVE DRIED UP THE GREEN TREE. This is Abimelech. (Ibid., cont.:) HAVE MADE THE WITHERED TREE BUD. This is Sarah. (Ibid., cont.:) I THE LORD HAVE SPOKEN, AND I WILL ACT. Thus it is stated (in Gen. 21:1): THEN THE LORD VISITED SARAH.
