Shalom Doves,
    As I read Dianne's post yesterday, it reminded me of the covenant of Abraham with the Jebusites....I found this in the explanitory notes from the Tanach on  2nd. Samuel 5:6
    first the scripture:  "The king and his men went to Jerusalem, to the Jebusite inhabitants of the land, and (one of them) spoke to David saying, "You shall not enter here unless you remove the blind and the lame," as if to say, "David will not enter here."  7) David then captured Zion Fortress, which is  (called) the City of David.  8) David declared on that day, "Whoever smites the Jebusite and reaches the stronghold, and the blind and the lame, that David  detest....!  Therefore (people) say , "The blind and the lame (are here);  he shall not enter the house!  9) David settled in the fortress and called it "The City of David."   David built around  (the city), from the Millo and inward.  10) David kept becoming greater, and Hashem, the G-d of Legions , was with him."

The Tenach notes:  "5:6--"This city is so well fortified that you could not conquer it even if it were guarded only by the blind  and the lame"   (Abarbanel).  According to the Midrash, the Jebusites alluded to the Patriarchs.  Abraham had made a treaty of peace with Abimelech, a Jebusite ancestor (Gen. 21:23).  To commemorate the binding nature of the treaty, the Jebusites set up statues of a Blind man, alluding to the Blind Isaac (see Gen. 27:1), and a Cripple, alluding to Jacob (see Gen. 32:26), and placed the words of the treaty in the statues'  mouths.
    5:7 notes: " The phrase is left unfinished (common practice for exclamations, curses and oaths in the Bible), but is quoted in full in 1st. Chronicles 11:6: "Whosever strikes the Jebusites first will become a chief and an officer."  David was no longer bound by Abraham's  oath because more than 700 years had passed, ("my son and my grnadson") and the term of the oath had expired.
    5:9  notes "The Millo was a landfill (Rashi), an open plaza for large gatherings (Radak), or a moat (Abarbanel)."

    My notes:  So here we have the general history of the Gihon Springs and the Pool of Siloam.  The Jews also believe that since the Gihon flowed out of Eden...that when it was the "Endtimes"...when life was restored as at the beginning, it would center around this Gihon Spring.  To see the story/teaching on this look at:
http://www.ohrtorahstone.org.il/parsha/5764/bereishit64.htm
   and:
http://www/us-israel.org/jsource/Archaeology/jerwater.html
    In an article at:
http://jeru.huji.ac.il/eb26.htm
    It states that in 1880 a boy who was bathing in the waters of the Gihon Spring found the inscription, now known as the Hezekiah's Tunnel Inscription.....written in the oldes Hebrew Alef-bet.   This is what gave me the connection to the date of the Venus Transit in 1882, when the Jewish Nation began coming back to the Holy Land.
    But, I had known of the Hezekiah Stone...but not as being joined to the Pool of Siloam.  As I read more on this...in a book titled "The Temples that Jerusalem Forgot" By Ernest L. Martin...I learned something more important.  The author of the book, puts forth proof...that the Temple Mount as known today, is NOT the Temple Mount of the 1st. and 2nd. Temples.....he gives as reasoning..that this Gihon Springs was within the HOLY OF HOLIES.  It is quite lengthy...and you would have to read all of his reasoning to follow, but it is a book well worth your getting.  If for no other reason, than to help you realize the Temple Mt. of today, and the Temple Mt. of David and Solomon are not the Same.  In reading it, you can see, why they have JUST FOUND the POOL OF SILOAM.
    Especially why the healing of the Blind and the Lame is prophetic of our times.  Remember the scripture that tells us that "Every Eye shall SEE!"  and the 1000 years of Peace and no death etc. etc.
    There are many Rabbit Trails to this story, and I am only beginning to get the picture.

Shalom,
Meriam Brown
