'Lions' in the Bible

who through faith did subdue kingdoms, wrought righteousness, obtained promises, stopped mouths of lions,

and they had hair as hair of women, and their teeth were as those of lions,

And thus I saw the horses in the vision, and those sitting upon them, having breastplates of fire, and jacinth, and brimstone; and the heads of the horses are as heads of lions, and out of their mouths proceedeth fire, and smoke, and brimstone;
