I had a good idea what your subject when I saw the scripture. Definitely a big problem for many. Some believe that she was sacrificed. What seems to be more of a majority is that she remained a virgin for life.
I find the Bible often records the negatives of Israel's history as well as the positive. Which is quite different from many of todays nations which seem to exclude the negative in their personal history.
Another thought was of Jesus telling us not to make Oaths.
"Again, you have heard that it was said to the people long ago, ‘Do not break your oath, but fulfill to the Lord the vows you have made.’ But I tell you, do not swear an oath at all: either by heaven, for it is God’s throne; or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. And do not swear by your head, for you cannot make even one hair white or black. All you need to say is simply ‘Yes’ or ‘No’; anything beyond this comes from the evil one (Matthew 5:33-37).
Also James probably reflecting on the above wrote.
"Above all, my brothers and sisters, do not swear--not by heaven or by earth or by anything else. All you need to say is a simple 'Yes' or 'No.' Otherwise you will be condemned" (James 5:12).
