And the war began again, and David went out and fought against the Philistines, and defeated them with a great slaughter, and they fled from his face.

And there addeth to be war, and David goeth out and fighteth against the Philistines, and smiteth among them, a great smiting, and they flee from his face.

And there was war again: and David went out fighting the Philistines, causing great destruction among them; and they went in flight before him.

Then the war was stirred up again. And David went out and fought against the Philistines. And he struck them down with a great slaughter. And they fled from his face.

And there was war again,.... Between Israel and the Philistines; it does not appear that either of them sent out their whole force, only some parties or detachments, between which there were skirmishes:
and David went out and fought with the Philistines; he went out with his thousand men, over which he was made captain, 1-Samuel 18:13; for he had not the command of the whole army; that belonged to Abner:
and slew them with a great slaughter, and they fled from him; he killed many of them in his engagements with them, and the rest fled, and he returned victorious; which stirred up the envy and increased the jealousy of Saul, to observe which this is related.

SAUL'S MALICIOUS RAGE BREAKS OUT AGAINST DAVID. (1-Samuel 19:8-17)
David went out, and fought with the Philistines, and slew them with a great slaughter--A brilliant victory was gained over the public enemy. But these fresh laurels of David reawakened in the moody breast of Saul the former spirit of envy and melancholy. On David's return to court, the temper of Saul became more fiendish than ever; the melodious strains of the harp had lost all their power to charm; and in a paroxysm of uncontrollable frenzy he aimed a javelin at the person of David--the missile having been thrown with such force that it pierced the chamber wall. David providentially escaped; but the king, having now thrown off the mask and being bent on aggressive measures, made his son-in-law's situation everywhere perilous.

Another great defeat which David had inflicted upon the Philistines excited Saul to such an extent, that in a fit of insanity he endeavoured to pierce David with his javelin as he was playing before him. The words Ruach Jehovah describe the attack of madness in which Saul threw the javelin at David according to its higher cause, and that, as implied in the words Ruach Jehovah in contrast with Ruach Elohim (1-Samuel 18:10; 1-Samuel 16:15), as inflicted upon him by Jehovah. The thought expressed is, that the growth of Saul's melancholy was a sign of the hardness of heart to which Jehovah had given him up on account of his impenitence. David happily escaped this javelin also. He slipped away from Saul, so that he hurled the javelin into the wall; whereupon David fled and escaped the same night, i.e., the night after this occurrence. This remark somewhat anticipates the course of the events, as the author, according to the custom of Hebrew historians, gives the result at once, and then proceeds to describe in detail the more exact order of the events.

And David, &c. - So David continues his good service, tho' it was ill requited. They who are ill paid for doing good, yet must not be weary of well doing, remembering how bountiful a benefactor God is, even to the evil and unthankful.
