In the Bible, a lion represents many things such as strength, fearlessness, ferocity and destruction. Lions are often used throughout the Bible in literal and figurative ways.
In Job 38:39-40 and Psalm 104:21, the lion, with all its strength, is still seen as a creature that is dependent on God and answerable to him. Figuratively, the lion is used to describe God in several passages. In Hosea 5:14 for example, God is described as being as destructive as a lion.
A lion's behavior is used to describe others besides God. In Proverbs 19:12, the king is frightening in his behavior, like a lion and in Psalm 10:9 and 17:12, enemies are sneaky and stealthy in their pursuit as a lion is when it is stalking its prey.
Lions are often portrayed as killers in the Bible. In 1 Kings 13:1-24, an unnamed prophet is eaten by lions after he was told by God not to eat bread but he did anyway. In 1 Kings 20: 35-36, another man is killed by a lion when he refused to strike a prophet. Finally, in 2 Kings 17: 25-26, a group of foreigners was killed by a pack of lions for refusing to worship God.
