'Lions' in the Bible

Who through faith subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions,

And they had hair as the hair of women, and their teeth were as the teeth of lions.

And thus I saw the horses in the vision, and them that sat on them, having breastplates of fire, and of jacinth, and brimstone: and the heads of the horses were as the heads of lions; and out of their mouths issued fire and smoke and brimstone.
