Mishnayos Sanhedrin Perek 11 Mishnah 6

One who prophesies in the name of idol worship and says: This is what the idol said, even if he approximated the correct halakha in the name of the idol to deem ritually impure that which is ritually impure and to deem ritually pure that which is ritually pure, is executed by strangulation. In the case of one who engages in intercourse with a married woman once she entered her husband’s domain for the purposes of marriage, even if the marriage was not yet consummated, as she did not yet engage in intercourse with him, one who engages in intercourse with her is executed by strangulation. Before marriage, one who engages in intercourse with her is liable to be executed by stoning. And conspiring witnesses who testified that the daughter of a priest committed adultery are executed by strangulation, even though were she guilty, she would be executed by burning. And her paramour is also executed by strangulation, as in any case where one engages in intercourse with a married woman. As all those who are rendered conspiring witnesses are led to their deaths via the same mode of execution with which they conspired to have their victim executed, except for conspiring witnesses who testified that the daughter of a priest and her paramour committed adultery. In that case, although the priest’s daughter who commits adultery is executed by burning, the conspiring witnesses who sought to have her executed are executed by strangulation, as is the paramour whom they also conspired to have executed.
