“The wheel of justice turns slowly,
but it grinds exceedingly small.”

The first person to make that observation was Sextus Empiricus, who wrote, “The mills of the gods grind slowly, but they grind small.” He lived in the early 3rd century AD, possibly late 2nd century.

Older still is the 37th Psalm, written by King David in his old age, around 970 B.C.  Multiple times and in different ways, he says, “Don’t fret yourself. They’re not getting away with it. Their end is coming and you will see it.” Justice is often delayed
because the wheel is slow. But it always arrives.
