Still Waters Run Deep

There are over 700 brands of bottled water currently on the market in the United States. Each brand claims to offer the perfect water taste. In ancient times, one would have assumed that there was no choice of water. Whatever well the water carrier drew his water from, that was the water you drank. However, that was not necessarily the case.
The Gemara in Yevamos (78b) relates an incident that took place during the rule of Dovid HaMelech. There was a famine in Eretz Yisrael due to the lack of rain. Dovid HaMelech theorized that there are three sins that could possibly be the cause of the drought: (a) idolatry, (b) immoral and promiscuous behavior, or (c) the failure of people to follow through with their pledges for charity.
After three years of thorough investigation, Dovid HaMelech concluded that Klal Yisrael was free of these sins. Realizing that he could not ascertain the reason that Hashem was causing the famine, he turned to the Urim v’Tumim. It turns out that there were two causes for the famine: The first reason was as a punishment for the fact that King Shaul was not eulogized properly as befitting a tzaddik of his stature. The second reason was as a punishment for the complicity that King Shaul had in causing the death of members of the nation of Givonim.
