How exciting that you are getting ready to “tie the knot”. In marriage, a knot is tied when there’s a desire for something to never come undone. In ancient times, whenever a covenant was established, there was typically a shedding of blood in order to seal the covenant. This was a symbolic gesture that basically communicated “I am willing to have my blood shed if I break this oath” or “the only way this oath can be broken will be upon the pain of death”.
