I just remember vauguely a scripture in the bible that says to shake off the dust from your shoes if someone rejects your message, as a testament against them. Or something along those lines. My husband and I joked that the missionaries shook their shoes after our encounter with them once.
I'm not sure if these are curses but I recall the "weeping and wailing and gnashing of teeth" at the loss of Christ's light or some such, and another thing about hanging a millstone around one's neck and jumping into the sea. How about, "I hope you have a daughter just like yourself one day!" <--- Or is that universal?
Jesus was saying that a millstone should be tied around people's necks that offend little ones.
Sunshine, you are referring to the practice I just learned (heard) about. It was told to me that when a missionary scraps their shoes (after they proselytizing, and your rejection of their words as truth), they curse you with the cleaning of their shoes as they leave. The person who shared this with me claimed to have heard this through another protestant ministry. I was shocked by the use of the word "curse." And, then it got me to wondering if there were any other such things going on.
Thanks for your answers.
Blessings to all.
Here is an interesting explanation on Wikipedia: http://en.wikipedia.org/wiki/Shaking_the_dust_from_the_feet
I remember it being discussed in the mission field (Scotland 1965). I don't remember the details, but I think we were to use it only in extreme cases.
