A.T. Robertson Commentary Mark 7:34

"and looking up to heaven, he sighed, and saith unto him, Ephphatha, that is, Be opened." — Mark 7:34 (ASV)

Ephphatha (διανοιχθητ, be opened). Another one of Mark's Aramaic words preserved and transliterated and then translated into Greek. "Be thou unbarred" (Braid Scots). Jesus sighed (εστεναξεν) as he looked up into heaven and spoke the word εφφαθα. Somehow he felt a nervous strain in this complex case (deaf, dumb, demoniac) that we may not quite comprehend.
