Deuteronomy 17:4-6

Complete Jewish Bible

⁴ and it is told to you, or you hear about it; then you are to investigate the matter diligently. If it is true, if it is confirmed that such detestable things are being done in Isra’el; ⁵ then you are to bring the man or woman who has done this wicked thing to your city gates, and stone that man or woman to death. ⁶ The death sentence is to be carried out only if there was testimony from two or three witnesses; he may not be sentenced to death on the testimony of only one witness.
