Thou shalt not muzzle the ox when he treadeth out the corn. Bible (Old Testament) Deuteronomy 25:4.
I put the
muzzle of the revolver into my right ear and pulled the trigger
I was out by one. I remember an extraordinary sense
of jubilation, as if carnival lights had been switched on in
a drab street. My heart knocked in its cage, and life
contained an infinite number of possibilities. (Henry) Graham Greene Recalling a game of Russian roulette with his brother's
revolver in1923. A
Sort of Life, ch.6, pt.2.
