You are right, those words are mentioned many times. Here is the list from Strong’s Exhaustive Concordance of the Bible: 1 Kings 14:19, 29; 15:7, 31; 16:5, 14, 20, 27; 22:39, 45; 2 Kings 1:18; 8:23; 10:34; 12:19; 13:8, 12; 14: 15, 18, 28; 15:6, 11, 15, 21, 26, 31, 36; 20:20; 21:17, 25; 23:28; 24:5; 1 Chronicles 27:24; Nehemiah 12:23; and Esther 2:23; 6:1; 10:2. What exactly is the “book of Chronicles?” We get some light on this question in Esther 2:22-23, “So the matter became known to Mordecai, who when an inquiry was made into the matter, it was confirmed, and both were hanged on a gallows; and it was written in THE BOOK OF CHRONICLES IN THE PRESENCE OF THE KING.” Here is what we read on this verse from “What the Bible Teaches”: “The events were then all recorded in the book of chronicles before the king, a ROYAL DIARY in which accounts of the daily affairs of the kingdom were preserved for posterity.” This king was not a “king of Israel or Judah” but he kept a detailed account of his reign, and this was the purpose of the “chronicles of the kings of Israel and Judah” as well.  They do NOT refer to 1st and 2nd Chronicles which were divinely inspired and thus made part of Holy Scripture for ALL TO READ. God tells us WHAT WE NEED TO KNOW and thus it was not His will to have the “chronicles of the kings of Israel and Judah” included in Holy Scripture.

If one has a problem accepting this, I will now quote two very well-known passages that shed light on this truth. In John 20: 30-31 we read, “And truly Jesus did many other signs in the presence of His disciples, WHICH ARE NOT WRITTEN IN THIS BOOK; but these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name.” This teaches us that Jesus Christ performed many other miracles, but God inspired John to write exactly WHAT WE NEEDED TO KNOW to bring us to “faith in Jesus Christ” so we could “have life in His name.”

John ended his inspired writings in John 21:24-25 with these words: “This is the disciple who testifies of these things and WROTE THESE THINGS; and we know that his testimony is true. And there are also MANY OTHER THINGS THAT JESUS DID, WHICH IF THEY WERE WRITTEN ONE BY ONE, I SUPPOSE THAT EVEN THE WORLD ITSELF COULD NOT CONTAIN THE BOOKS THAT WOULD BE WRITTEN.” Our God is a very “practical God” who has inspired men to write the exact words we needed to hear or read. If He were to have inspired men to write, in detail, of every miracle Jesus did and every word that Jesus spoke, the world’s libraries could not contain them (nor would one have the time to read them in their lifetime).

Again, God has given us, in the Holy Scriptures, EXACTLY WHAT WE NEED to be saved and to then “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Peter 3:18). I think it is fitting to close with 2 Timothy 2:15-17, “from childhood you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.”  (DO)  (717.1)
