The Israelite legal requirement for multiple witnesses to any criminal charge goes back to the Law of Moses and the book of Numbers, but is itself restated many times in scripture. By the time we encounter it in the New Testament from the apostle Paul, there is a new twist on the “two or three” rule. “This is the third time I am coming to you,” he writes. “Every charge must be established by the evidence of two or three witnesses.”
Did you catch that? In this case the three witnesses are all the same person. I don’t know about you, but I’m pretty sure that’s not precisely what God intended.
