I've posted this prophecy before, but just saw a different article on it that had some new information.

According to the new article, the 2nd part is slightly different:
If the ships of the Kingdom of Russia cross the Bosphorous Straits (in Northwest Turkey), we need to put on our Shabbat clothes, because this is telling you that the coming of the Messiah is very close.
The article states that this happened two months ago:
It's an interesting read and potentially very telling if true. Here's the link:
