well

cistern

Definition:

The terms "well" and "cistern" refer to two different kinds of sources for water in Bible times.

A well is a deep hole dug into the ground so that underground water can flow into it.
A cistern is a deep hole dug into rock that was used as a holding tank for collecting rain water.
Cisterns were usually dug into rock and sealed with plaster to keep the water in. A "broken cistern" happened when the plaster became cracked so that the water leaked out.
Cisterns were often located in the courtyard area of people's homes to catch the rainwater that would run off the roof.
Wells were often located where they could be accessed by several families or a whole community.
Because water was very important for both people and livestock, the right to use a well was often a cause of strife and conflict.
Both wells and cisterns were usually covered with a large stone to prevent anything falling in it. Often there was a rope with a bucket or pot attached to it to bring the water up to the surface.
Sometimes a dry cistern was used as a place to imprison someone, such as happened to Joseph and Jeremiah.

Ways to translate "well" could include "deep water hole" or "deep hole for spring water" or "deep hole for drawing water."
The term "cistern" could be translated as "stone water pit" or "deep and narrow pit for water" or "underground tank for holding water."
These terms are similar in meaning. The main difference is that a well continually receives water from underground springs, whereas a cistern is a holding tank for water that usually comes from rain.
