'Lion' in the Bible

Even he who is valiant, whose heart is as the heart of a lion, will utterly melt; for all Israel knows that your father is a mighty man, and those who are with him are valiant men.

Benaiah the son of Jehoiada, the son of a valiant man of Kabzeel, who had done mighty deeds, he killed the two [sons of] Ariel of Moab: he went down also and killed a lion in the midst of a pit in time of snow.
