'Lions' in the Bible

Saul and Jonathan were lovely and pleasant in their lives, and in their death they were not divided: they were swifter than eagles, they were stronger than lions.

Then even men who would otherwise be as brave as lions will be scared, because every Israeli knows your father is a mighty man, and they know his men are valiant!

And Benaiah the son of Jehoiada, son of a valiant man, great in exploits, of Kabzeel: he it was that smote two lions of Moab; and he went down and smote a lion in the midst of a pit on a snowy day.
