TEFE - It is interesting how you made the connection between Genesis 49:10 and celestial signs. This verse was the focus of THE transitional point for for me back in 1991 as it was revealed to me how it described a key celestial sign of the last days. You can read avout the details in http://theopenscroll.com/beyond_veil/year1991.htm .  There is a preliminary presentation of some vital background info here: http://theopenscroll.com/when_jesus_was_born.htm .
 
Shabbat Shalom!
