Haman takes the advice of his family and friends, preparing the gallows to hang Mordecai. Now there is two things we need to look at here that Haman does not know, or at least I do not think he had a clue. Number one, it seems he had no idea that Esther was a Jew. And number two, the most critical, he does not see God.
Believe it or not, the process of hanging someone is somewhat of an art or it may be better described as involving quite a bit of physics. Thanks to my researcher (again Ali), she found this article. In preparing the gallows, the hangman had to take several factors into account. Number one, the height of the person to be hanged. Number two, the correct amount of drop. Number three, the stretch factor. And number four, the knot had to be tied just in a special way as well.
Now, it is hard to believe that it is this technical. For instance, someone 6 feet tall, you would add 7 feet per drop and another 6 feet per stretch. Hence, the gallows should be about 19 feet from the ground. The reason it is so precise is that without proper drop, the neck would not break properly and it would take the subject 15 minutes to die. Too much drop and it is rather self-explanatory. It would just rip someone's head off, creating a huge mess, as the article said. Sorry for the gruesome explanation, but I wanted to show the hatred that Haman had for Mordecai because he wanted to rip his head off ordering the gallows to be 50 cubits high or 75 feet. I think that is probably about five of these buildings. I forgot to measure it. Four times the recommended height for a 6 foot man.
