since we're talking about heavenly horses, i should put these here; they belong in that conversation:
Then it happened, as they continued on and talked, that suddenly a chariot of fire appeared with horses of fire, and separated the two of them; and Elijah went up by a whirlwind into heaven.
And Elisha saw it, and he cried out, “My father, my father, the chariot of Israel and its horsemen!” So he saw him no more. And he took hold of his own clothes and tore them into two pieces.
(2 Kings 2:11-12)
So he answered, “Do not fear, for those who are with us are more than those who are with them.”
And Elisha prayed, and said, “LORD, I pray, open his eyes that he may see.”
Then the LORD opened the eyes of the young man, and he saw: and behold! The mountain was full of horses and chariots of fire all around Elisha!
(2 Kings 6:16-17)
