And when the king of Moab saw that the battle was too sore
The siege was so close, the slingers or engineers did so much execution, that he saw the city would soon be taken, and he be obliged to deliver it up:
he took with him seven hundred men that drew
men expert in war, bold and daring:
to break through even unto the king of Edom;
through his quarters, and so escape, he lying nearest to the city, and perhaps the weakest body of men with him; or he might think he was not so hearty in the cause of the kings, and would make but a feeble resistance, and let him pass:
but they could not;
break through they met with a greater opposition than was expected perhaps the Edomites remembered how they had lately used them, which made them fight more desperately against them, see ( 2 Chronicles 20:23 ) .
