19 Of Manasseh also there fell away some to David, when he came with the Philistines against Saul to battle; but they didn't help them; for the lords of the Philistines sent him away after consultation, saying, "He will fall away to his master Saul to the jeopardy of our heads."

And there fell [some] of Manasseh to David, when he came with the Philistines against Saul to battle: but they (f) helped them not: for the lords of the Philistines upon advisement sent him away, saying, He will fall to his master Saul to [the jeopardy of] our heads.
(f) They came only to help David, and not to help the Philistines, who were enemies of their country.
And there fell some of Manasseh to David,.... Of the tribe of Manasseh; they took his part, and on his side, and joined him:
when he came with the Philistines against Saul to battle; which was a strong proof of their cordial attachment to him:
but they helped them not: the Philistines; neither David nor his men, nor the Manassites that joined them:
for the lords of the Philistines, upon advisement; counsel taken among themselves: sent him away; that is, David and his men:
saying, he will fall to his master Saul, to the jeopardy of our heads; meaning, that he would go off with his troops to Saul, and betray them into his hands, and with their heads make his peace with him, see 1-Samuel 29:4.

The Manassites who went over to David before the last battle of the Philistines against Saul. - על גפל, to fall to one, is used specially of deserters in war who desert their lord and go over to the enemy: cf. 2-Kings 25:11; 1-Samuel 29:3. אל יפּול, in the last clause of the verse, is a synonymous expression. The Manassites went over "when David went with the Philistines against Israel to the war, and (yet) helped them not; for upon advisement (בּעצה, cf. Proverbs 20:18), the lords of the Philistines had sent him away, saying, 'For our heads, he will fall away to his master Saul.' " 1-Samuel 29:2-11 contains the historical commentary on this event. When the lords of the Philistines collected their forces to march against Saul, David, who had found refuge with King Achish, was compelled to join the host of that prince with his band. But when the other Philistine princes saw the Hebrews, they demanded that they should be sent out of the army, as they feared that David might turn upon them during the battle, and so win favour by his treachery with Saul his lord. See the commentary on 1-Samuel 29:1-11. בּראשׁנוּ, for our heads, i.e., for the price of them, giving them as a price to obtain a friendly reception from Saul (cf. 1-Samuel 29:4). In consequence of this remonstrance, Achish requested David to return with his warriors to Ziklag. On this return march ("as he went to Ziklag," cf. with בּלכתּו the ללכת of 1-Samuel 29:11), and consequently before the battle in which Saul lost his life (Berth.), and not after Saul's great misfortune, as Ewald thinks, the Manassites whose names follow went over to David. The seven named in 1-Chronicles 12:20 were "heads of the thousands of Manasseh," i.e., of the great families into which the tribe of Manasseh was divided, and as such were leaders of the Manassite forces in war: cf. Numbers 31:14 with Exodus 18:25, and the commentary on the latter passage.
