In Camus book "the plague", the narrator is describing burial ceremonies.so after placing coffin in the grave,There is sentence which I don't understand
"No sooner had the priest begun to sprinkle holy water than the first sod rebounded from the lid".
I know sod is a part of turf.but how is it rebounded when priest sprinkle holy water. Is sod on the coffin so when water is sprinkled, it falls off. TIA
