I put my life in my hands - Compare 1 Samuel 19:5; 1 Samuel 28:21. The phrase expresses the utmost possible risk, knowingly incurred.

I put my life in my hands - I exposed myself to the greatest difficulties and dangers. But whence did this form of speech arise? Probably from a man's laying hold of his sword, spear, or bow. "This is the defender of my life; on this, and my proper use of it, my life depends." When a man draws his sword against his foe, his enemy will naturally aim at his life; and his sword in his hand is his sole defense. It is then, Fight and conquer, or die. Thus Jephthah took his life in his hand. This phrase occurs in some other places of Scripture; see 1 Samuel 19:5; 1 Samuel 28:21. And the words of the Conqueror, Isaiah 63:5, seem to confirm the above view of the subject: I looked, and there was none to help; and I wondered there was none to uphold; therefore mine own arm brought salvation unto me; i.e., by mine own arm I saved my life, and brought destruction on mine enemies.

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, Judges 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.

And when I saw that ye delivered me not, {c} I put my life in my hands, and passed over against the children of Ammon, and the LORD delivered them into my hand: wherefore then are ye come up unto me this day, to fight against me?

(c) That is, I ventured my life, and when man's help failed, I put my trust only in God.

12:3 Put my life - That is, I exposed myself to the utmost danger; as a man that carries a brittle and precious thing in his hand, which may easily either fall to the ground, or be snatched from him. Wherefore - Why do you thus requite my kindness in running such hazards to preserve you and yours?

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.

12:1-7 The Ephraimites had the same quarrel with Jephthah as with Gideon. Pride was at the bottom of the quarrel; only by that comes contention. It is ill to fasten names of reproach upon persons or countries, as is common, especially upon those under outward disadvantages. It often occasions quarrels that prove of ill consequence, as it did here. No contentions are so bitter as those between brethren or rivals for honour. What need we have to watch and pray against evil tempers! May the Lord incline all his people to follow after things which make for peace!
