If we are generally familiar with the Old and New Testaments, we know that “it is written” references in the New Testament often are not literal word-for-word matches to the source in the Old Testament.
The entire Bible – from Genesis 1:1 to Revelation 22:21 – is inspired by God (2 Timothy 3:16). He breathed his word into Moses and John and everyone in between, so that the words are pure, accurate, inerrant, and authoritative. Therefore, any New Testament quotes of, references to, or allusions to the written Old Testament are inspired by God. For that reason, we should consider how God inspired men to quote, reference, and allude to his inspired words. Such has authority over our thoughts, opinions, explanations, and illustrations on the same (which thoughts and opinions we often have too much admiration for).
