And when he opened the first seal, I Heard:

Head, neck, hair, ears, eyes, eye fringes, iris of the eye, eyebrows, mouth, tongue, lips, teeth, roof of the mouth, jaws and the jaw-hinges, nose, nostrils of the nose and the partition, cheeks, temples, forehead, chin, throat, back of the neck, neck-slue, strong shoulders, manly beard, scapula.

Back of the neck, strong shoulders, do you hear me? Strong shoulders, manly beard, scapula. Ladies and gentlemen, do I hear: hind-shoulders, and the ample side-round of the chest,
Wrist and wrist-joints.
[hey, I’m on it]
Yes sir, wrist and wrist-joints. Hand, knuckles, thumb, forefinger, finger-balls, finger-joints, finger-nails.
[Ooh, I like that one]
Yes, sir. Probably you have the best. Breast-bone, breast-side, ribs, belly, backbone, hips, man-++, man-++. Ooh, that’s a strong set of thighs, well carrying the trunk above.
[++++]
Leg-fibers, knee, upper-leg, under-leg, Do you hear me? Going, going, going, stop!

Nose, nostrils of the nose...
- Water poured over the nose and mouth
...and the partition, cheeks, temples, forehead, chin, throat, back of the neck, neck-slue...
- Collar around the neck to bang the head and body against the wall.
…strong shoulders…
- Perforated shoulder.
manly beard…
- Forced shaving of the head and beard.
…scapula, hind-shoulders, and the ample side-round of the chest. Upper-arm, armpit, elbow-socket, lower-arm, arm-sinews, arm-bones, wrist and wrist-joints.
