No, I don't think that's true. Num. 30:3 and Deut. 23:22-24 requires fulfilling oaths made to G-d.
That is right. When a person, such as Jeph-thah made a promise/vow to God they are obligated to keep their promise/vow, to God.
But however does this mean, that when a person, such as Jeph-thah made his promise/vow, without actually knowing who may walk out the door of his house.
Does this mean that Jeph-thah daughter is also obligated to keep the promise/vow, that her father made without her being aware about such a promise/vow, her father made, between him and God.
Does this mean that Whosoever can make a promise/vow, to God that they can involves you, does that mean your obligated to keep the promise/vow also. Without you being unaware of such a promise/vow.
Alot of Christians believe, God gave each person, "Free Will" to make their own choices in life.
When Jephthah told his daughter about the promise/vow that he made to God.
Seeing how Jephthah daughter told her father that she needed two months to think about the matter.
Now while she was away for two months, She took upon herself
"Free Will" to determined whether she wanted to partake with her fathers promise/vow to God. Unto which she didn't make, but her father made the promise and not her.
It was her "Free Will" to make that decision for herself.
Let's for say, When she came back to her father and she told her father no.
Nothing could happen to her, seeing that she's not the one who made the promise/vow to God, But her father made the promise/vow to God.
So nothing could possibly happen to her, without violating her "Free Will" to make her own choices.
Therefore her father nor God could force her into doing something, without violating her Free Will. To make her choices, whether she wanted to or not wanting to.
So this is why, she went away for two months, to think the matter out, So she could by her Free Will, determine her own choice.
Otherwise people could go about making promises/vows and including someone else in their promise/vow to God and that person is obligated to keep the promise/vow also.
So how would you feel, if someone made a promise/vow to God, and you had no idea about.
So would you give your life because they made a promise/vow that you were unaware about.
What about your "Free Will" to choose for yourself whether you want to or not?
