Charles Ellicott Commentary Mark 7:35

"And his ears were opened, and the bond of his tongue was loosed, and he spake plain." — Mark 7:35 (ASV)

His ears.—Literally, his hearing, or, as the word is in the plural, his organs of hearing.

The string of his tongue.—Better, bond, that which confined and hampered his speech. . There is no ground for thinking that St. Mark used the word in any anatomical sense, as the English word seems to suggest, for a “nerve” or “tendon,” as in the “eye-strings” of the original text of the “Rock of Ages.”
