“Woe to the worthless shepherd
who leaves the flock!
The sword will fall on his arm
and on his right eye.
His arm will be completely withered,
and his right eye will be totally blinded!” Bible other translations

“right eye.” The right eye was invaluable to the warrior because in order for the body to be protected in war the shield had to be mostly in front of the warrior, covering the left eye. If the right eye was blind, the warrior had to move the shield so far to the left to see to fight that the shield became essentially useless (cp. 1 Sam. 11:2).
