שְׁאָגָ֥ה ל֖וֹ כַּלָּבִ֑יא ושאג [יִשְׁאַ֨ג] כַּכְּפִירִ֤ים וְיִנְהֹם֙ וְיֹאחֵ֣ז טֶ֔רֶף וְיַפְלִ֖יט וְאֵ֥ין מַצִּֽיל׃
O seu rugido é como o do leão; rugem como filhos de leão; sim, rugem e agarram a presa, e a levam, e não há quem a livre.
Rashi
אוני means MY VIGOR, as (Hosea 12:9) “I have gained me (און) strength”; (Isaiah 40:26) “by the greatness of His (אונים) might”; (Isaiah 5:29) “and to him that hath no (אונים) might Ho increaseth strength”.
Rashi
Will a lion roar in the forest if he has no prey—When a lion lays hold of its prey, it customarily roars, and it does not roar unless it has taken [prey]. Similarly, Scripture states: (Isa. 5:29) “He will roar like the lion cubs, and he will growl and lay hold of prey.” Similarly, (ibid. 31:4) “As a lion or a young lion growls over his prey.”
