and the curse, if ye shall not hearken to the commandments of LORD your God, but turn aside out of the way which I command you this day to go after other gods, which ye have not known.

If there be found in the midst of thee, within any of thy gates which LORD thy God gives thee, man or woman, who does that which is evil in the sight of LORD thy God, in transgressing his covenant, and has gone and served other gods, and worshipped them, or the sun, or the moon, or any of the host of heaven, which I have not commanded, and it be told thee, and thou have heard of it, then shall thou inquire diligently. And, behold, if it be true, and the thing certain, that such abomination is wrought in Israel,read more.
then thou shall bring forth that man or that woman, who has done this evil thing, to thy gates, even the man or the woman, and thou shall stone them to death with stones. At the mouth of two witnesses, or three witnesses, shall he who is to die be put to death. He shall not be put to death at the mouth of one witness.

They shall not dwell in thy land, lest they make thee sin against me, for if thou serve their gods, it will surely be a snare to thee.

But the prophet, who shall speak a word presumptuously in my name, which I have not commanded him to speak, or who shall speak in the name of other gods, that same prophet shall die.
