Shilo/Marqe As 'Unsheather of the Cross'

The old Samaritan Hebrew to Aramaic dictionary of the Torah glosses Shilo as “the unsheather of the cross”. Any suggestions? Ben-Hayyim, followed like a sheep as usual by Tal (who should have copied Ben-Hayyim’s thoroughness and rigour but didn’t) translates “the uprooter of the cross” saying (as a mere guess) that it refers to Muhammad. This makes no sense. How could the rise of Islam have been what took the sceptre away from Judah? The verb shin-lamed-pe usually means to unsheathe a sword, but can mean to take a shoe off or to pull something out of the ground. I think the plain meaning is that the reference is to whoever unsheathed the cross and used it like a sword to take power away from Judah or the Jews, but I can’t work out what exactly is meant.
