Rabbi Yochanan and the Widow Who Walked to a Far Shul
Rabbi Yochanan sees a widow davening in his neighborhood and asks why she doesn't use the shul near her home. She answers that there is reward for the extra steps.
Rashi explains that Rebbe Yochanon came to this conclusion by witnessing the actions of a widow. One day, Rebbe Yochanon saw her davening in his neighborhood. He asked her, “Isn’t there a shul in your neighborhood?” She replied, “But isn’t there a reward for the additional steps?”
