Murrain
The word "murrain" is an antiquated term covering various infectious diseases affecting cattle and sheep. The word originates from Middle English moreine or moryne, in parallel to Late Latin, a probable derivative of Latin .
The word "murrain", much like the word "pestilence", did not refer to a specific disease but rather served as an umbrella term for what veterinary science now recognises as a number of different diseases with high morbidity and mortality, such as rinderpest, erysipelas, foot-and-mouth disease, anthrax, and streptococcus infections. Some of these livestock diseases can also affect humans. The term "murrain" also referred to an epidemic of such a disease.
There were major sheep- and cattle-murrains in Europe during the 14th century, which, combined with the Little Ice Age, resulted in the Great Famine of 1315–1317, weakening the population of Europe before the onset of the Black Death in 1348.
Biblical references
The term murrain is also used in some Bible translations relating to the fifth plague brought upon Egypt.Exodus 9:3: "Behold, the hand of the LORD is upon thy cattle which is in the field, upon the horses, upon the asses, upon the camels, upon the oxen, and upon the sheep: there shall be a very grievous murrain."
"Pestilence", which is mentioned 47 times in 46 verses of the Bible, can be translated "murrain" by Christian apologists.
