Mark 6:31

Come ye yourselves apart into a desert place and rest awhile (Deute umei autoi kat idian ei erhmon topon kai anapauesqe oligon). It was plain that they were over-wrought and excited and needed refreshment (anapauesqe, middle voice, refresh yourselves, "rest up" literally). This is one of the needed lessons for all preachers and teachers, occasional change and refreshment. Even Jesus felt the need of it. They had no leisure so much as to eat (oude pagein eukairoun). Imperfect tense again. Crowds were coming and going. Change was a necessity.
