The art of the Biblical chronologist or Date-finder is a mystery to most, so let me explain how such a date can be found. Firstly, I will take a brief look at the assumptions or starting points which I will use.
I must assume or believe to be true that the information about dates does exist in the Bible (otherwise I would not start to look).
I must assume that such information is reliable and the writers did not set out to deceive. (This assumption must be made about any historical document before it is examined.) Therefore if I find apparent contradictory evidence in the text, I will first assume that a problem exists in my understanding rather than the text.
Thirdly, I assume that since the Bible is God’s revealed word to man, it is accurate and therefore will not conflict with true historical information derived from outside the Biblical text.
Lastly, I assume that the best way of using information from one part of the Bible is to use it the way the Biblical writers used it or referred to it in other parts of the Bible.
