Those same phrases of clean and unclean (in Hebrew, טהור and טמא, Vulgate: mundus and inmundus) appear in Leviticus chapter 11, with lists and guidelines regarding certain animals. For example, "Every animal that parts the hoof but is not cloven-footed or does not chew the cud is unclean" (Lev. 11:26 ESV). The camel, hyrax (or rock badger), hare, and pig are all "unlcean" (11:4-8). "And these are unclean to you among the swarming things that swarm on the ground: the mole rat, the mouse, the great lizard of any kind, 30 the gecko, the monitor lizard, the lizard, the sand lizard, and the chameleon (11:29-30).
The context is a list of animals that may or may not be eaten, as well as what "should be detestable to you", i.e. not to be touched (See Leviticus beginning of chapter 5 and chapter 7:19-21). However, these phrases are never used in the context of what may or may not be offered to God as a sacrifice.
