Blessings sister,
I found this on horses:
http://www.acts17-11.com/dialogs_horses.html
Horses are used in the main to represent a carnal strength, a trusting in flesh; relied on by the enemies of God to their peril. Along this line:
In the modern sense, a good equivalent for horses would be money. It is that which we put our confidence, our hope... outside of (or in competition with) the Lord.
Beyond "horses" in plural, a real, individual horse is used as a negative image of the spiritually dull person--along with the mule and donkey--as one who does not (or cannot) understand the will of the Lord.
Thank you Cizz....I'm deep in study now searching for "horses and chariots." The problem with the above definition is that there are also "horses and chariots" of God. Both sides have them (actually...that phrase is how I'm begining my thread on that topic.) So, I may well use what you have provided but there is still more to discover. So much to learn and so little time. Please let me know anything else on this topic you discover....it is very appreciated. 
I see what you mean! But could the chariots also mean ..materialistic confidence? one is flesh and one is material...just a thought
