How could one chase a thousand ... Yahweh had given them up?

How could one chase a thousand, and two put ten thousand to flight

"How could 1 enemy soldier chase 1,000 of your men, and 2 enemy soldiers cause 10,000 of your men to run away"

unless their Rock had sold them

"unless Yahweh, their Rock, had handed them over"
