Judges 11:30 Meaning and Commentary

Judges 11:30

And Jephthah vowed a vow unto the Lord
Before he set out for the land of the children of Ammon, and to fight with them; hoping that such a religious disposition of mind would be regarded by the Lord, and be acceptable to him, and he should be blessed with success in his enterprise:

and said, if thou shall without fail deliver the children of Ammon into
mine hands;
though he was assured of the justness of his cause, and of his call to engage in it, he seems to have some little diffidence in his mind about the success of it; at least, was not fully certain of it.

Judges 11:30 In-Context

28 But the king of the children of Ammon hearkened not to the words of Jephthah that he had sent him.

29 Then the Spirit of Jehovah came upon Jephthah, and he passed through Gilead and Manasseh, and passed to Mizpeh of Gilead, and from Mizpeh of Gilead he passed over to the children of Ammon.

30 And Jephthah vowed a vow to Jehovah, and said, If thou wilt without fail give the children of Ammon into my hand,

31 then shall that which cometh forth from the door of my house to meet me, when I return in peace from the children of Ammon, be Jehovah's, and I will offer it up for a burnt-offering.

32 And Jephthah passed over to the children of Ammon to fight against them; and Jehovah gave them into his hand.
