To break through, even unto the king of Edom - Either because he thought that the king of Edom would connive at his escape or to take vengeance on him for having deserted his former allies (2 Kings 3:8 note).

Seven hundred men - These were no doubt the choice of all his troops, and being afraid of being hemmed up and perhaps taken by his enemies, whom he found on the eve of gaining possession of the city, he made a desperate sortie in order to regain the open country; and supposing that the quarter of the Edomites was weakest, or less carefully guarded, he endeavored to make his impression there; but they were so warmly received by the king of Edom that they failed in the attempt, and were driven back into the city. Hence he was led to that desperate act mentioned in the following verse.

And when the king of Moab saw that the battle was too sore for him,.... 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 swords; 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.

When the king of Moab saw that the battle was too strong for him, he attempted to fight a way through the besiegers with 700 men with drawn swords (להבקיע, lit., to split them) to the king of Edom, i.e., on the side which was held by this king, from whom he probably hoped that he should meet with the weakest resistance.

And when the king of Moab saw that the battle was too sore for him, he took with him seven hundred men that drew swords, to break through even unto the king of Edom: but they could not.

3:26 To break thro' - That he might make an escape: which he chose to do on the king of Edom's quarter; because he thought his was the weakest side.

3:20-27 It is a blessing to be favoured with the company of those who have power with God, and can prevail by their prayers. A kingdom may be upheld and prosper, in consequence of the fervent prayers of those who are dear to God. May we place our highest regard upon such as are most precious in his account. When sinners are saying Peace, peace, destruction comes upon them: despair will follow their mad presumption. In Satan's service and at his suggestion, such horrid deeds have been done, as cause the natural feelings of the heart to shudder; like the king of Moab's sacrificing his son. It is well not to urge the worst of men to extremities; we should rather leave them to the judgment of God.
