The title of this post comes from 2 Corinthians 13:1 (21st Century King James Version).
2 Corinthians 13 (Holman Christian Standard Bible Version)
This is the third time I am coming to you. Every fact must be established by the testimony of two or three witnesses. 2 I gave a warning when I was present the second time, and now I give a warning while I am absent to those who sinned before and to all the rest: If I come again, I will not be lenient, 3 since you seek proof of Christ speaking in me. He is not weak toward you, but powerful among you. 4 In fact, He was crucified in weakness, but He lives by God’s power. For we also are weak in Him, yet toward you we will live with Him by God’s power.
5 Test yourselves to see if you are in the faith. Examine yourselves. Or do you yourselves not recognize that Jesus Christ is in you?—unless you fail the test. 6 And I hope you will recognize that we do not fail the test. 7 Now we pray to God that you do nothing wrong—not that we may appear to pass the test, but that you may do what is right, even though we may appear to fail. 8 For we are not able to do anything against the truth, but only for the truth.
9 In fact, we rejoice when we are weak and you are strong. We also pray that you become fully mature. 10 This is why I am writing these things while absent, that when I am there I will not use severity, in keeping with the authority the Lord gave me for building up and not for tearing down. 11 Finally, brothers, rejoice. Become mature, be encouraged, be of the same mind, be at peace, and the God of love and peace will be with you. 12 Greet one another with a holy kiss. All the saints greet you. 13 The grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with all of you.
15 “If your brother sins against you, go and rebuke him in private. If he listens to you, you have won your brother.
16 But if he won’t listen, take one or two more with you, so that by the testimony of two or three witnesses every fact may be established. 17 If he pays no attention to them, tell the church. But if he doesn’t pay attention even to the church, let him be like an unbeliever and a tax collector to you. 18 I assure you: Whatever you bind on earth is already bound in heaven, and whatever you loose on earth is already loosed in heaven. 19 Again, I assure you: If two of you on earth agree about any matter that you pray for, it will be done for you by My Father in heaven. 20 For where two or three are gathered together in My name, I am there among them.”
6 The one condemned to die is to be executed on the testimony of two or three witnesses. No one is to be executed on the testimony of a single witness.
15 “One witness cannot establish any wrongdoing or sin against a person, whatever that person has done. A fact must be established by the testimony of two or three witnesses.
The Lord Uses 2 Witnesses In Revelations “End Times”
The Two Witnesses
11 Then I was given a measuring reed like a rod, with these words: “Go and measure God’s sanctuary and the altar, and count those who worship there. 2 But exclude the courtyard outside the sanctuary. Don’t measure it, because it is given to the nations, and they will trample the holy city for 42 months. 3 I will empower my two witnesses, and they will prophesy for 1,260 days, dressed in sackcloth.” 4 These are the two olive trees and the two lampstands that stand before the Lord of the earth. 5 If anyone wants to harm them, fire comes from their mouths and consumes their enemies; if anyone wants to harm them, he must be killed in this way. 6 These men have the power to close up the sky so that it does not rain during the days of their prophecy. They also have power over the waters to turn them into blood and to strike the earth with every plague whenever they want.
