Isaiah 21:7

And he saw a chariot with a couple of horsemen, a chariot of asses, and a chariot of camels; and he hearkened diligently with much heed:

and when he sees a troop, horsemen in pairs, a troop of donkeys, a troop of camels, he shall listen diligently with much heed.

and when he seeth a troop, horsemen in pairs, a troop of asses, a troop of camels, he shall hearken diligently with much heed.

And he hath seen a chariot -- a couple of horsemen, The rider of an ass, the rider of a camel, And he hath given attention -- He hath increased attention!

When he sees chariots with teams of horsemen, riders on donkeys, riders on camels, he must be alert, fully alert.”
