Mark 7:32

Verse 32. They bring unto him one that was deaf, and had an impediment in his speech] Though from the letter of the text, it does not appear that this man was absolutely deprived of speech; for μογιλαλος literally signifies, one that cannot speak plainly - a stammerer; yet it is certain also that the word means a dumb person; and it is likely that the person in question was dumb, because he was deaf; and it is generally found that he who is totally deaf is dumb also. Almost all the versions understand the word thus: and the concluding words seem to confirm this - He maketh both the deaf to hear, and the DUMB, κωφους, to speak.
