'Lions' in the Bible

men who, as the result of faith, conquered whole kingdoms, brought about true justice, obtained promises from God, stopped lions' mouths,

Their faces seemed human and they had hair like women's hair, but their teeth resembled those of lions.

And this was the appearance of the horses which I saw in my vision--and of their riders. The body-armour of the riders was red, blue and yellow; and the horses' heads were shaped like the heads of lions, while from their mouths there came fire and smoke and sulphur.
