Yes I am sure. You seem to have the propensity to leave out certain parts of scripture so as to make it seem like it is not. Just before that in the prior verse it says " And it was a custom in Israel," This was not about keeping staying attached, but a custom to show respect for the dead. One proof is it was only women. This is just a custom with no particular emotional attachment. It was cultural and had no particular personal feeling. There is no suggestion this is how we are to be in fact this is much like the paid mourners during the time of Christ who would be bought and paid by the family for to weep at the funeral of someone and catch their tears in a jar to keep face that the person was loved. These woman in that passage you gave would not even have to know the dead woman intimately, it was a custom, not personal affection or attraction.
Lastly it does not suggest that it went on for more then a year and in fact we know it ended at some point. It was just a custom.
Judges 11:39-40 And it came to pass at the end of two months, that she returned unto her father, who did with her
according to his vow which he had vowed: and she knew no man. And it was a custom in Israel,
That the daughters of Israel went yearly to lament the daughter of Jephthah the Gileadite four days in a year.
Yes it was a custom; I never denied it wasn't. How does that change any thing? As to the time frame it doesn't give one. Perhaps one year, but unlikely. Customs usually last much longer than one year. The verse specifically says "went yearly" so we know that it was much longer than a year.
Regarding death. In mid-east and eastern nations, the people celebrated or remembered the death more than the birth of their loved ones. We even have this example in Christ himself. Early Christians never celebrated the birth of Christ and no such example is given in the Bible, but we are commanded to remember his death in the Lord's Supper. And we do, not only then, but also on Good Friday, and also in our baptism. Death to self is also emphasized throughout the Christian life.
We are commanded to be "Crucified with Christ." Paul said "I die daily". "Put the old man to death" "You are dead to sin."
Jesus said, "If any man will come after me let him deny himself,
take up his cross daily, and follow me" (Luke 9:23).
The cross is the instrument of death, of execution in the time of Christ. Christ died as a criminal on a cross. We are to die daily.
Death is referred to and emphasized in the Bible.
Those visiting the Holy Land seek out the site of where our Lord was buried.
Muslims seek out the site where Mohammed was buried.
--Neither seek the place of their births.
There are shrines dotting this world of "saints", prophets, wise men, leaders of various religions--of their burial places, but not of their birth places. People remember them in their death, not in their birth.
The next time the Hajj or Muslim Pilgrimage to Mecca takes place watch a channel that records what happens. See the mourning, wailing, the remembrance for their prophet.
