1 Samuel 6:5

Mice that mar the land. The idea of a plague of field mice is, as we have seen, due to one of those many unauthorised insertions of the Septuagint by which they supposed that they removed difficulties from the way of their readers. As the ancients use the names of animals in a very generic way, any rodent may be meant from the jerboa downwards; but probably it was the common field mouse, arvicola arvensis, still common in Syria, which multiplies with great rapidity, and is very destructive to the crops, and so became the symbol of devastation and pestilence (see on 1 Samuel 5:6 ). When, as Herodotus relates (Book 2:141), the Assyrian army of Sennacherib had been defeated, because a vast multitude of field mice had overrun his camp and gnawed asunder the bow strings of his troops, the Egyptians raised a statue to Hephaestus, holding in his hand a mouse. But very probably this is but the literal explanation by Herodotus of what he saw, while to a well instructed Egyptian it represented their god of healing, holding in his hand the mouse, as the symbol either of the devastation which he had averted, or of the pestilence with which he had smitten the Assyrian army (see on 1 Samuel 5:6 ).
