A book full of errors cannot be from God nor can have anything to do with God.
.....
What we have here? Mistranslation/misinterpretation? So
somehow someone mistranslated "began his reign" when he was 42 in lieu of "ended his reign when he was 42" - even though the verse itself states:
and he reigned one year in Jerusalem
Even ignoring the alleged mistranslation/misinterpretation: 22 + 1 = 42 according to their maths
Most scholars regard the 42 years in 2 Chronicles 22:2 as a copyist's error for an original 22 years.
The age of 22 is also found in some Greek and Syrian versions of 2 Chronicles 22:2.
Do you understand that? I doubt it. Because for the Muslim -- The Quran is the verbatim Arabic word of Allah. Any translation -- is interpretation. I hope you agree?
Now look how is it shooting Muslims in the foot. How can Quran be a message to humanity then? I don't speak Arabic. Why do I need to learn Arabic to learn about God?
Users here probably noticed by now that I prefer to use "Revelation" or "Message", instead of "Bible", when discussing the source of spiritual truth. Because Word of God is the Son of God and God Himself. Sinful man can speak one thing but be another thing in essence. Holy God cannot, while being omnipotent. Word of God is not a language, it is the Message, a Message than can be available in any form and any language. There are many translation of the word "mother", but only one essence of a mother being a mother, even for an infant who does not speak any language. The real Message from above is Love, for God is Love. Even infant gets it, he does not need to learn Arabic in order to get saved.
Bible did not arrive to us via fax machine from Heaven. God made sure that His will be known in written form for the people through the people during the period of many, many years. In this material world He does everything through material means, including crystallizing the Revelation in form of the written word. Matter, energy, information -- these are the three words that describe everything that exists in this material world, as opposed to spiritual world we will enter after this life. We do not worship the book, we worship living Word of God, God Himself, who reveals to us in this material world, not only in form of information, but also in form of the matter, His Body and His Blood, during the Holy Eucharist. God is everywhere, His Message is everywhere, as Fine Tuning Argument shows, for example, He does not begins and ends with an actual Book, no matter how holy it is.
Now, what happened to the Living Word of God, when He visited this Earth 2000 years ago? His material physical Body was damaged, nay, even put to death, but death could not erase Word of God from this material world. Resurrection started the Day 8 for this world, when the last enemy -- death and eternal damnation -- is defeated, if you accept the Living Word of God.
Just like with the skin of Jesus, which can be damaged by the nail, a single material letter in the the particular copy of material book representing spiritual Message can be damaged by the copyist. It is not 42, it is 22, and some other copies do have it right. Does this change Message? Does this kill Message? Only if you worship the book. Not when you seek the Living God Almighty.
