(10) Cursed be he . . .--To the prophet the destruction of the tyrannous haughtiness was a righteous retribution in which he saw the work of Jehovah, and he could not wish that it should be done otherwise than effectually. The thought rests on the belief in the Divine government that works through war as well as through pestilence and famine (Jeremiah 25:31; Jeremiah 46:10). (Comp. like utterances in Judges 5:23; 1Samuel 15:3; 1Samuel 15:18; 1Kings 20:42.) Even Christian nations fighting against slave-traders or pirates might legitimately echo the same prayer. It has been used, with less justification, in the religious wars of our own and other countries.

Verse 10. - Deceitfully; rather, slackly, negligently.

48:1-13. The Chaldeans are to destroy the Moabites. We should be thankful that we are required to seek the salvation of men's lives, and the salvation of their souls, not to shed their blood; but we shall be the more without excuse if we do this pleasant work deceitfully. The cities shall be laid in ruins, and the country shall be wasted. There will be great sorrow. There will be great hurry. If any could give wings to sinners, still they could not fly out of the reach of Divine indignation. There are many who persist in unrepented iniquity, yet long enjoy outward prosperity. They had been long corrupt and unreformed, secure and sensual in prosperity. They have no changes of their peace and prosperity, therefore their hearts and lives are unchanged, Ps 55:19.Cursed be he that doeth the work of the Lord deceitfully,.... Which is said with respect to the Chaldeans, who were enjoined to destroy the Moabites; which is called the work of the Lord, because he had given them a commission to do it; and which was to be done by them, not by halves, or in a remiss and negligent manner, but fully and faithfully; they were not to spare them, as Saul did the Amalekites, and Ahab Benhadad. This is a general rule, which may be applied to all divine work and service; every man has work to do for God; some in a more public, others in a more private way; all should be done in uprightness and sincerity, with all faithfulness and integrity: it is done deceitfully when men play the hypocrite; and negligently when they are backward to it, lukewarm in it, and infrequent in the performance of it; which brings upon them the curse of God; and which is not a curse causeless, but a legal one; and is no other than the wrath of God in strict justice:

and cursed be he that keepeth back his sword from blood; from shedding the blood of the Moabites, when God had given command to do it. The curse is repeated, as Kimchi observes, to confirm the matter, that it might be most assuredly expected; since it would certainly come, if the Lord's work was not done aright.
