I cut my teeth on the KJV. I don't find the KJV to be troublesome to read, I would go to a concordance to find the original word in Greek or Hebrew when I had a question or was seeking to understand the meaning of a verse which is why I read the Bible in the first place. I compare the KJV to about 10 translations, including the NKJV.
In my experience, God's Truth remains the same from the beginning to the end as He doesn't change. For instance, Jesus said;
Matt. 5:
31 (KJV) It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement: 32 But I say unto you, That whosoever shall put away his wife, "saving for the cause" of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
When I go to the Law and Prophets, here is what was commanded.
Deut. 24:1 (KJV)
When a man hath taken a wife, and married her, and it come to pass that she find no favour in his eyes, "because" he hath found some uncleanness in her: (fornication) then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.
So in the KJV, Jesus and Moses are on the exact same page concerning "divorce, or "putting away one's wife". Even to the point of it being the "Christ, the Word of God" who created this "saying" in the first place. (But I say)
Here are other translations.
NKJV. 31 "Furthermore it has been said, 'Whoever divorces his wife, let him give her a certificate of divorce.
32 But I say to you that whoever divorces his wife for any reason
except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery.
NIV. 31 “It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce. 32 But I tell you that anyone who divorces his wife,
except for sexual immorality, makes her the victim of adultery, and anyone who marries a divorced woman commits adultery.
NRS. 31 "It was also said, "Whoever divorces his wife, let him give her a certificate of divorce. 32 But I say to you that anyone who divorces his wife,
except on the ground of unchastity, causes her to commit adultery; and whoever marries a divorced woman commits adultery.
CLV.
31 "Now it was declared, Whoever should be dismissing his wife, let him be giving her a divorce.
32 Yet I am saying to you that everyone dismissing his wife
(outside of a case of prostitution) is making her commit adultery, and whosoever should be marrying her who has been dismissed is committing adultery.
And here are the same translations regarding Deut 24.
NKJV. 1 "When a man takes a wife and marries her, and it happens that she finds no favor in his eyes
because he has found some uncleanness in her, and he writes her a certificate of divorce, puts it in her hand, and sends her out of his house,
NIV. 1 If a man marries a woman who becomes displeasing to him
because he finds something indecent about her, and he writes her a certificate of divorce, gives it to her and sends her from his house,
NRS. 1 Suppose a man enters into marriage with a woman, but she does not please him
because he finds something objectionable about her, and so he writes her a certificate of divorce, puts it in her hand, and sends her out of his house; she then leaves his house
CLV.
1 When a man takes a wife and possesses her, and it comes to be that she should not find favor in his eyes,
because he has found in her the nakedness of anything, then he would write for her a scroll of divorce, give it into her hand and send her away from his house.
This lets me know, in some assurance, that Jesus and Moses were on the same page where "Divorce" in concerned, but was exposing a religious doctrine concerning divorce, that was not being taught by the mainstream religions of that time. I come to this conclusion by comparing several translations, including the NKJV.
I have no problem with it, I just like the KJV better by reason of use I guess.
