Okay. Now I know what you are talking about. Yes, this was a principle of the Law as well as the NT. No one could be condemned in a court of law on the testimony of only one witness. There could be more than three, but there had to be at least two.
And now I get what he's talking about
and that's a very enlightening thought. He will not condemn without warning his people
Amos 3:
3 Hear this word that the Lord hath spoken against you, O children of Israel, against the whole family which I brought up from the land of Egypt, saying,
2 You only have I known of all the families of the earth:
therefore I will punish you for all your iniquities.
3 Can two walk together, except they be agreed?
4 Will a lion roar in the forest, when he hath no prey? will a young lion cry out of his den, if he have taken nothing?
5 Can a bird fall in a snare upon the earth, where no gin is for him? shall one take up a snare from the earth, and have taken nothing at all?
6 Shall a trumpet be blown in the city, and the people not be afraid? shall there be evil in a city, and the Lord hath not done it?

Surely the Lord God will do nothing, but he revealeth his secret unto his servants the prophets.
So I liken the two witnesses to the watchman in Ezekiel 3
17 Son of man, I have made thee a watchman unto the house of Israel: therefore hear the word at my mouth, and give them warning from me.
18 When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand.
19 Yet if thou warn the wicked, and he turn not from his wickedness, nor from his wicked way, he shall die in his iniquity; but thou hast delivered thy soul.
20 Again, When a righteous man doth turn from his righteousness, and commit iniquity, and I lay a stumbling-block before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteousness which he hath done shall not be remembered; but his blood will I require at thine hand.
21 Nevertheless if thou warn the righteous man, that the righteous sin not, and he doth not sin, he shall surely live, because he is warned; also thou hast delivered thy soul.
