In regards to the issue of the NIV being skewed, consider Leviticus 11:20
In the NIV, it is written in Leviticus 11:20 All flying insects that walk on all fours are to be regarded as unclean by you.
In the KJV, it is written in Leviticus 11: 20 All fowls that creep, going upon all four, shall be an abomination unto you.
Since the flying creeping things and the fowls are two distinct classes, separated not only by their description but also the day of their creation then the translation of the NIV is flawed since it erroneously redefines the fowl as a flying insect.
In Genesis 1:20-21 it is written:
20 And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven.
21 And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good.
Then in Gen 1:24-25 it is written:
24 And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.
25 And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good.
Consider the format of Leviticus 11: Verse 2 begins with the instructions regarding the beasts that are 'on' the earth.
2 Speak unto the children of Israel, saying, These are the beasts which ye shall eat among all the beasts that are on the earth.
3 Whatsoever parteth the hoof, and is clovenfooted, and cheweth the cud, among the beasts, that shall ye eat.
4 Nevertheless these shall ye not eat of them that chew the cud, or of them that divide the hoof: as the camel, because he cheweth the cud, but divideth not the hoof; he is unclean unto you.
5 And the coney, because he cheweth the cud, but divideth not the hoof; he is unclean unto you.
6 And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you.
7 And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you.
8 Of their flesh shall ye not eat, and their carcase shall ye not touch; they are unclean to you
And thus verse 8 concludes the instructions regarding the beasts that are upon the earth.
Thus in Leviticus 11:9-12 as an example of the format: Verse 9 begins with the instruction regarding aquatic creatures:
9 These shall ye eat of all that are in the waters: whatsoever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat.
10 And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you:
11 They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcases in abomination.
12 Whatsoever hath no fins nor scales in the waters, that shall be an abomination unto you.
And thus verse 12 concludes the instructions regarding aquatic life
In Leviticus 11:13-20, verse 13 begins the instructions regarding the fowls
13 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 ospray,
14 And the vulture, and the kite after his kind;
15 Every raven after his kind;
16 And the owl, and the night hawk, and the cuckow, and the hawk after his kind,
17 And the little owl, and the cormorant, and the great owl,
18 And the swan, and the pelican, and the gier eagle,
19 And the stork, the heron after her kind, and the lapwing, and the bat.
20 All fowls that creep, going upon all four, shall be an abomination unto you.
Thus, verse 20 concludes the instructions regarding the fowls.
Thus, in Leviticus 11:21-23, it begins with the instructions regarding of flying insects
21 Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap withal upon the earth;
22 Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind.
23 But all other flying creeping things, which have four feet, shall be an abomination unto you.
Thus, verse 23 concludes the instructions regarding the flying insects.
Lev 11:29-31
29 These also shall be unclean unto you among the creeping things that creep upon the earth; the weasel, and the mouse, and the tortoise after his kind,
30 And the ferret, and the chameleon, and the lizard, and the snail, and the mole.
31 These are unclean to you among all that creep: whosoever doth touch them, when they be dead, shall be unclean until the even.
So it is pretty obvious that the NIV mistranslated the passage of Leviticus 11:20, yet according to the NIV, can you name one flying insect that walks on all fours which is to be regarded as unclean by you? [This is going to be extremely difficult since all flying insects have 6 legs, but that would shut me up if you can name one flying insect that has four legs.]
