6And aElam bore the quiver
with chariots and horsemen,
and bKir uncovered the shield.
7Your choicest valleys were full of chariots,
and the horsemen took their stand at the gates.

8Come now, make a wager with my master the king of Assyria: I will give you two thousand horses, if you are able on your part to set riders on them.
