“After this I beheld, and lo another, like a leopard, which had upon the back of it four wings of a fowl; the beast had also four heads; and dominion was given to it.”
King James Version (KJV)
7:6 Like a leopard - This leopard was the Grecian monarchy; a leopard is less than a lion, so was this monarchy at first, but yet durst fight with a lion; so did Alexander encounter Darius with an inferior force. A leopard also for his swiftness; therefore described with four wings on his back. Four heads - He was succeeded by four of his chief commanders, who divided that empire into four parts.
