Most of you, by now, have heard the words Elenin and Nibiru.  The discussion about Elenin is quite familiar also, some believe there is an actual person, an amateur astronomer in Russia, Leonid Elenin, , who "discovered" what was to become known as Comet Elenin; while others believe the ELE in Elenin stands for Extinction Level Event, while the NIN in Elenin may mean Nibiru is Near; and others who say the ELE short for Eleven, the NIN is short for Nine, and these reference, backward, the infamous day in US history: 9/11. 

These are all generally known theories, but less well known is what Nibiru may mean.  It may be interesting, especially if you are thinking that Nibiru may have a connection to the event known as the Rapture, to find in an article written by Michael S. Heiser,(Ph.D. candidate, Hebrew Bible and Ancient Semitic Languages, University of Wisconsin-Madison), that the meaning of the word Nibiru has been found to be: a crossing; a gateway; or the act of (or related to) ferrying:

        Word meaning, of course, is determined by context.  “Nibiru” (more technically and properly transliterated as “neberu”[5]) can mean several things.  I have underlined the form of nibiru for the reader:

“place of crossing” or “crossing fee” – In the Gilgamesh epic,[6] for example, we read the line (remarkably similar to one of the beatitudes in the sermon on the Mount): “Straight is the crossing point (nibiru; a gateway), and narrow is the way that leads to it.”  A geographical name in one Sumero-Akkadian text, a village, is named “Ne-bar-ti-Ash-shur” (“Crossing Point of Asshur”).  Another text dealing with the fees for a boatman who ferries people across the water notes that the passenger paid “shiqil kaspum sha ne-bi-ri-tim” (“silver for the crossing fees”).

“ferry, ford”; “ferry boat”; “(act of) ferrying” – For example, one Akkadian text refers to a military enemy, the Arameans: “A-ra-mu nakirma bab ni-bi-ri sha GN itsbat”[7] (“The Arameans were defiant and took up a position at the entrance to the ford [gate, crossing point]”).  In another, the Elamites are said to “ina ID Abani ni-bi-ru u-cha-du-u”  (“[to] have cut off the ford [bridge, crossing way] of the river Abani”)...
