This statement is made in Leviticus 11:6, where the Hebrew literally means "raises up what has been swallowed." The rabbit does re-eat partially digested fecal pellets that come from a special pouch called the caecum. Bacteria in these pellets enrich the diet and provide nutrients to aid digestion. According to the Encyclopedia Britannica: "Some lagomorphs [rabbits and hares] are capable of re-ingesting moist and nutritionally rich fecal pellets, a practice considered comparable to cud-chewing in ruminants ...The upper tooth rows are more widely separated than the lower rows, and chewing is done with a transverse movement."
