There are only a few verses on this subject. Let's examine them and let the Bible reveal what these verses address.Let's check all the verses about being a witness.
(reference 1) Numbers 35:30 (& Deuteronomy 17:6) Whoso killeth any person, the murderer shall be put to death by the mouth of witnesses; but one witness shall not testify against any person to cause him to die.Analysis:
Other verses on this subject2 Corinthians 13:1 This is the third time I am coming to you. In the mouth of two or three witnesses shall every word (Strong's 4487 again) be established.
1 Timothy 5.19 Against an elder receive not an accusation, but before 2 or 3 witnesses.
Hebrews 10:28 He that despised Moses's law died without mercy under 2 or 3 witnesses.
These are all the relevant verses in the bible on this topic. In each case it is talking about flesh and blood witnesses to something that was said or done.
Can this same concept be used to establish a doctrine?NO!
We do not have permission to take a few verses and develop a pet doctrine.IT IS DANGEROUS AND IS LIKELY TO LEAD TO DOCTRINAL ERROR.
As I said before, we must round up all the Biblical data on the particular subject and analyze them as a whole. Be like the Bereans and study. (2 Timothy 2:15.)
By taking each verse in context to the chapter or historical setting you can develop the real meaning.
In addition, none of the verses can contradict each other. We also need to study any qualifications in the passages such as if you do this I will do that. This keeps us from taking verses out of context and trying to make them say what they do not say.We don't want to isolate a passage, text, sentence, or word from its literary context.
