'Lion' in the Bible

And even the one who is brave, whose heart is like the heart of a lion, will completely lose heart and melt away; for all Israel knows that your father is a mighty man, and that those who are with him are brave men.

Then Benaiah the son of Jehoiada, the son of a valiant man of Kabzeel, who had done many notable acts, killed two [famous] warriors of Moab. He also went down and killed a lion in the middle of a pit on a snowy day.
