It provides only those details that are necessary to make the point. Archaeology can often recover the evidence necessary to help to fill in the gaps and add color to the images we already have. The Bible does not describe what Jesus was doing between the age of 12 and the time be began His ministry 18 years later. This helps to make the Bible come alive. Fourth, what we have exposed through archaeology, in the way of both biblical and non-biblical manuscripts, helps us in the translation and explanation of many passages.
Words can and do change their meanings over the years.
Sometimes we will find a word in a manuscript written in a similar language, with another meaning that fits the Biblical context better. So this helps us to get a better idea of exactly what the author meant by the use of a particular word. The Egyptian papyri have contributed a great deal to our understanding and knowledge of the world of the New Testament. They have also served to illustrate the language and thought of the common people and thus, the New Testament Church. In addition, the Dead Sea Scrolls have helped to underscore the hand of God in getting his word down to us over a period of hundreds of years.
