Richter 12:3

when I saw that ye delivered me not, I put my life in my hands--A common form of speech in the East for undertaking a duty of imminent peril. This Jephthah had done, having encountered and routed the Ammonites with the aid of his Gileadite volunteers alone; and since the Lord had enabled him to conquer without requiring assistance from any other tribe, why should the Ephraimites take offense? They ought rather to have been delighted and thankful that the war had terminated without their incurring any labor and danger.

And when I saw that ye delivered me not,.... Gave him no assistance against their common enemy, did not attempt to save him and his people out of their hands, but left them to defend themselves: I put my life in my hands; ready to deliver it up in the defence of his country; the meaning is, that he exposed himself to the utmost danger, hazarded his life in going with a few troops into an enemy's country to fight him, and so liable to lose his life; which was in as much danger, as some observe, as any brittle thing contained in the hand is in danger of falling, or of being snatched out of it: and passed over against the children of Ammon: took a long and fatiguing march over the land of Gilead into that of the children of Ammon, to fight with them: and the Lord delivered them into my hand; gave him victory over them, which showed that his cause was just, and his call to engage in it clear: wherefore then are ye come up unto me this day to fight against me? who rather should have come with thanks to him for the service he had done, not only for the Gileadites, but for all Israel; for had he not fought against the children of Ammon, and conquered them, they would have soon not only overrun and oppressed Gilead, but would have come over Jordan, and dispossessed the other tribes, and particularly Ephraim, as they had done already, Jdg 10:9 so that it was base ingratitude in these people to come to fight against Jephthah, who had fought for them, and wrought salvation for them.

When the Gileadites had beaten the Ephraimites, they took the fords of the Jordan before the Ephraimites (or towards Ephraim: see Jdg 3:28; Jdg 7:24), to cut off their retreat and prevent their return to their homes. And "when fugitives of Ephraim wanted to cross, the men of Gilead asked them, Art thou Ephrathi," i.e., an Ephraimite? And if he said no, they made him pronounce the word Shibboleth (a stream or flood, as in Psa 69:3, Psa 69:16; not an ear of corn, which is quite unsuitable here); "and if he said, Sibboleth, not taking care to pronounce it correctly, they laid hold of him and put him to death at the fords of the Jordan." In this manner there fell at that time, i.e., during the whole war, 42,000 Ephraimites. The "fugitives of Ephraim" were the Ephraimites who had escaped from the battle and wished to return home. The expression is used here in its ordinary sense, and not with the contemptuous sense in which the Ephraimites had used it in Jdg 12:4. From this history we learn quite casually that the Ephraimites generally pronounced sh (shin) like s (samech). הכין is used elliptically for לב הכין, to direct his heart to anything, pay heed (compare Sa1 23:22; Ch1 28:2, with Ch2 12:14; Ch2 30:19).

In this chapter we have, I. Jephthah's rencounter with the Ephraimites, and the blood shed on that unhappy occasion (Jdg 12:1-6), and the conclusion of Jephthah's life and government (Jdg 12:7). II. A short account of three other of the judges of Israel: Ibzan (Jdg 12:8-10), Elon (Jdg 12:11, Jdg 12:12), Abdon (Jdg 12:13-15).
