According to Leviticus 11:27 the lion is an unclean animal because of its paw. Therefore, how is it that the lion (Lion of the Tribe of Judah) is chosen as a type of Christ?
Unclean animals are a classification in regards to food. "Nevertheless these you shall not eat among those that chew the cud or those that have cloven hooves: the camel, because it chews the cud but does not have cloven hooves, is unclean to you" (Leviticus 11:4). For example, a camel is unclean in regards to being food, but it was still used to transport people and goods across the desert.
