Mouse, rat
Animals in the Bible
It would not be possible to describe here all the various rodents covered by the Hebrew word ‘akbar. The descriptions will thus be limited to rats, voles, jerboas, and gerbils. House mice and field mice are too well known all over the world to warrant description.
Rats are larger than mice (25-30 centimeters [1 foot] long including tail) but otherwise look very much like them. Both the Black Rat Rattus rattus and the Brown Rat Rattus norvegicus vary in color from black to grayish brown with the brown rat having a slightly shorter snout. The black rat is host to a certain type of flea that is a carrier of the dreaded bubonic plague. Although zoologists in the 1960’s believed that Rattus rattus originated in Asia remains of this rat have been found in Israel dating from prehistoric times. The Brown Norwegian Rat only arrived in the land in the 1930’s.
Levant VoleMicrotus socialis guentheri: Voles differ from small mice only in the shape of their cheek teeth so to most people they look just like mice. They are small grayish brown and have pale bellies. They feed on grass stalks and the stalks of grains such as wheat and barley. They are active day and night for about two or three hours at a time eating their own body weight and more each day. They also produce up to sixteen litters a year with up to twelve babies in a litter. Thus in a good season when there is plenty of food and cover in which to hide from predators their population explodes and this vast increase in numbers poses a very serious threat to crops. Of all mice these are the most destructive.
Lesser JerboaJaculus jaculus: The scientific name means “jumper". Jerboas are slightly larger than most mice and have very long hind legs and very short front legs. They hop like kangaroos and are even known (erroneously) as “kangaroo rats". They have a long tail with a tuft at the end and this is used for balance when they hop. They live in desert and semidesert areas and are the color of sand. They are active only at night and have large eyes and ears to compensate for this. They feed on seeds and can go without water for long periods.
Palestinian GerbilGerbillus andersoni allenbyi: Gerbils are very similar to jerboas but are smaller. When alarmed they can move very fast covering up to 3 meters (10 feet) with each leap. Although called “sand rats” or “desert rats", they are actually not rats at all in the strict sense of the word.

What it stands for
In the ‘akbar is listed as an unclean animal. It is not clear and has often been debated by rabbinic scholars whether all “mice” are included in the ban, or only some species. Jerboas, gerbils, and hamsters are a common food among Middle Eastern desert tribes and are not classified as “mice” today.
More about it
The Hebrew word ‘akbar is a very general one including all of the small rodents. The word thus includes house mice, field mice, voles, dormice, jerboas, jirds, gerbils (sand or desert rats), black rats, brown rats, hamsters, and others. The Canaanites hunted and ate the larger rodents such as jerboas and gerbils (which are not rats at all, in spite of their nickname “sand rats"), and so do many of the desert tribes today in the Middle East.
