John 5:8

The impotent man having declared his helplessness, Jesus says to him, Ἔγειρε, a command to be obeyed on the moment by faith in Him who gave it. Cf. John 6:63, and Augustine's “Da quod jubes, et jube quod vis”. ἆρον τὸν κράββατόν σου, “take up your pallet”. κράββατος is the Latin grabatus, and is late Greek; see Rutherford's New Phryn., 137; and McLellan's Greek Test., p. 106, for references and anecdote. He was commanded to take up his bed that he might recognise that the cure was permanent. No doubt many of the cures at the pool were merely temporary. περιπάτει “walk,” ability was given not merely to rise, but to walk. The cures wrought by Christ are perfect, and do not only give some relief.
