Your scripture is out of text. I am curious where you got that? What version?
Deuteronomy 18:20 (King James Version)
20But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.
As you can see, this is not a commandment, but a statement from God. It implies that judgement is from God, not man. Unlike the version you quote where it states it as an instruction. Very misleading. I advise to leave that alone.
Exodus 22:20 (King James Version)
King James Version (KJV)
20He that sacrificeth unto any god, save unto the LORD only, he shall be utterly destroyed
Deuteronomy 17:2-7 (King James Version)
2If there be found among you, within any of thy gates which the LORD thy God giveth thee, man or woman, that hath wrought wickedness in the sight of the LORD thy God, in transgressing his covenant,
3And hath gone and served other gods, and worshipped them, either the sun, or moon, or any of the host of heaven, which I have not commanded;
4And it be told thee, and thou hast heard of it, and enquired diligently, and, behold, it be true, and the thing certain, that such abomination is wrought in Israel:
5Then shalt thou bring forth that man or that woman, which have committed that wicked thing, unto thy gates, even that man or that woman, and shalt stone them with stones, till they die.
6At the mouth of two witnesses, or three witnesses, shall he that is worthy of death be put to death; but at the mouth of one witness he shall not be put to death.
7The hands of the witnesses shall be first upon him to put him to death, and afterward the hands of all the people. So thou shalt put the evil away from among you.
