Come unto me (deute pro me). Verses 28 to 30 are not in Luke and are among the special treasures of Matthew's Gospel. No sublimer words exist than this call of Jesus to the toiling and the burdened (peportismenoi, perfect passive participle, state of weariness) to come to him. He towers above all men as he challenges us. "I will refresh you" (kago anapausw ma). Far more than mere rest, rejuvenation. The English slang expression "rest up" is close to the idea of the Greek compound ana-pauw. It is causative active voice.
