“Bear” [3:10]. The Holy One has become like a bear to me and like a lion from concealment.
Rashi
He is a bear lying in wait for me. The Holy One, Blessed Is He, turned into a bear in wait for me.7Alternatively, bear refers to Nevuchadnetzar who lay in wait to attack the Bnei Yisroel who are symbolized by a lion. (Eichah Rabbah 3:4)
