So there was just a thunderstorm, and my sister came with a question I couldn't answer:
Why is it "thunder and lightning", because the lightning comes before the thunder? Shouldn't it be "lightning and thunder"?
And now I wonder, where did the phrase "thunder and lightning" come from, and why isn't it "lightning and thunder"?
Best Answer
In the Latin bible, it is written in Exodus 19:16-25:
A widespread translation in the English Bible is:
The literal translation of "audiri tonitrua ac micare fulgura" is "hear thunder and see lightning" in this precise (chronologically erroneous) order. We may imagine that today expression thunder and lightning is related to this bible sentence.
EDIT: The whole New Testament was initially written in Greek, whilst the vast majority of the Old Testament was written in Hebrew. Exodus being a part of the Old Testament, the origin of the text is probably Hebrew. The Hebraic Bible was translated to Greek in the 3rd century BC. The first translation from Greek to Latin was the Vulgate by St. Jerome at end of the 4th century AD.
