5727 was a big year for Israel - they took back Jerusalem in the 6-day war. Adding up the numbers is 21 or 3 sevens.
i wonder if 5772 (those numbers also add up to 21), which begins in Fall 2011, will also be a big year for them. Perhaps the temple will be rebuilt in that year?
Just a thought.
Btw, 5709 (also adds up to 21) was the year that began in the Fall of 1948, making it the first full year during which Israel was once again a physical nation.
