Acts 9:33 New English Translation

³³He found there a man named Aeneas who had been confined to a mattress for eight years because^[a] he was paralyzed.

Acts 9:33 tn Since the participle κατακείμενον (katakeimenon), an adjectival participle modifying Αἰνέαν (Ainean), has been translated into English as a relative clause (“who had been confined to a mattress”), it would be awkward to follow with a second relative clause (Grk “who was paralyzed”). Furthermore, the relative pronoun here has virtually a causal force, giving the reason for confinement to the mattress, so it is best translated “because.”
