'Testimony of Two or Three Witnesses' in the Bible

Based on the testimony of two or three witnesses, they must surely die. But they are not to die based on the testimony of one person.

"The testimony of one person alone is not to suffice to convict anyone of any iniquity, sin, or guilt. But the matter will stand on the testimony of two or three witnesses.

But if he doesn't listen, take one or two others with you so that "every word may be confirmed by the testimony of two or three witnesses.'

Anyone who violates the Law of Moses dies without mercy "on the testimony of two or three witnesses."
