A.T. Robertson Commentary Acts 9:34

"And Peter said unto him, Aeneas, Jesus Christ healeth thee: arise and make thy bed. And straightway he arose." — Acts 9:34 (ASV)

Healeth (ιατα). Aoristic present middle indicative, heals here and now.

Make thy bed (στρωσον σεαυτω). First aorist (ingressive) active imperative of στρωννυμ (-υω). Old word with "bed" (κραβαττον) understood as the object. Literally, spread thy bed for thyself (dative case), what others for eight years have done for thee.
