Water seeps in through the porous stone at the bottom of it.
Rain falls from the heavens in due season, and the water rests in the well waiting for the thirsty.
Jacob's well sits at a fork in the road. The sun stands straight overhead. Jesus, a Jew, stops in this Samaritan territory while his disciples look for food. All who travel this day have hunger, heat and thirst as their companions. These things are common ties.
