In the Portion of Masey we are given a list of all the places that Bnei Israel traveled and camped when they left Egypt on their way to the Promised Land. In one particular verse we read that they journeyed from Marah and they came to Eilim where, we are told, there were SHTEIM ESRE EINOT MAIM, “…twelve wells of water”.(Num. 33,9)
They had come from Marah. The name means bitter and the place was so named because of the fact that the waters there were bitter. When the Israelites got there they complained to Moshe that they had no water and Moshe was instructed by Hashem to cast a tree into the water. When he did so the waters became drinkable.
The Chafetz Chaim pointed out that had the people had a little patience they would have come to Eilim where there were twelve wells and plenty of water. He makes the point that people should not be impatient. With a little SAVLANUT many of our problems could be solved.
