As the media reported about a huge sinkhole which appeared in a town in Germany, this week's parsha deals with Yitzchok digging holes to be used as underground wells.
After Yitzchok moved from downtown Grar to the valley because of jealousy of the local people, the Pilishtim continued to harass him and stuff up up his wells. This whole episode is recorded in the Torah, and is one of the few stories we have about Yitzchok. Why is this so significant?
Rabbeinu Bachaye tells us that these Be'er Mayim Chaim refer to the Bais HaMikdash, which is the source of Mayim Chaim or Hashem. The first one representing the first Bais HaMikdash, was called Aisek, because it was the subject of a number of wars and attacks until it was finally stuffed up or destroyed and the Shechina no longer flowed through there. The second one was called Sitna, as in Satan or obstruction. Achashveirosh obstructed its building, and there were always obstructionists during its entire existence, until it too was finally destroyed.
The third well was called Rechovos because Hashem gave us room and let us blossom. This refers to the third Bais HaMikdash in which there will be no opposition. In describing this well, the torah uses Hashem's name, "Ki Hirchiv Hashem Lanu". Because unlike the first two that were built by man (Shlomo and Koresh respectively), the third Bais HaMikdash will be built by Hashem.
