For someone who reads the Bible I would expect you to know what verses I was referring to. But since you insist, let's just stick with Leviticus (because there is a many, many more), 11:13-19.
"And these are they which ye shall have in abomination among the fowls ; they shall not be eaten, they are an abomination: the eagle, and the ossifrage, and ... the stork, the heron after her kind, and the lapwing, and the bat."
In fact, the very next set of verses continues in the same manner:
Lev 11:20 "11:20 All fowls that creep, going upon all four, shall be an abomination unto you."
Creeping fowls? Four-legged fowls?
Or, you may go a few verse up, to Leviticus 11:6 and read
"And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you."
is a mnay = are many
This is your evident that the Bible is in error? Classification of animals is a manmade invention based upon some criteria. The criteria used back then was different than it is today. Consider what Aristotle states about the bat:
You cannot make a case of the Bible being in error simply based upon some way people classified animals back then. The writers simply used the current definition of the day.
