'Lion' in the Bible

See, Israel comes up like a she-lion, lifting himself up like a lion: he will take no rest till he has made a meal of those he has overcome, drinking the blood of those he has put to death.

He took his sleep stretched out like a lion, and like a she-lion: by whom will his rest be broken? May a blessing be on everyone who gives you blessing, and a curse on everyone by whom you are cursed.
