Deuteronomy 17
v.6
On the testimony of two or three witnesses a man shall be put to death, but no one shall be put to death on the testimony of only one witness.
v.7
The hands of the witnesses must be the first in putting him to death, and then the hands of all the people. You must purge the evil from among you.
v.12-13
The man who shows contempt for the judge or for the priest who stands ministering there to the LORD your God must be put to death. You must purge the evil from Israel. 13All the people will hear and be afraid, and will not be contemptuous again.
v.16-17
The king, moreover, must not acquire great numbers of horses for himself or make the people return to Egypt to get more of them, for the LORD has told you, “You are not to go back that way again.” 17He must not take many wives, or his heart will be led astray. He must not accumulate large amounts of silver and gold.
v.18-20
When he takes the throne of his kingdom, he is to write for himself on a scroll a copy of this law, taken from that of the priests, who are Levites. 19It is to be with him, and he is to read it all the days of his life so that he may learn to revere the LORD his God and follow carefully all the words of this law and these decrees 20and not consider himself better than his brothers and turn from the law to the right or to the left. Then he and his descendants will reign a long time over his kingdom in Israel.
