'Lion' in the Bible

And David said to Saul, Your servant has been keeper of his father's sheep; and if a lion or a bear came and took a lamb from the flock,

Your servant has overcome lion and bear: and the fate of this Philistine, who is without circumcision, will be like theirs, seeing that he has put shame on the armies of the living God.

And David said, The Lord, who kept me safe from the grip of the lion and the bear, will be my saviour from the hands of this Philistine. And Saul said to David, Go! and may the Lord be with you.
