TSK · Leviticus 20:10

Moreover thou shalt not lie carnally with thy neighbour's wife, to defile thyself with her.

If a man be found lying with a woman married to an husband, then they shall both of them die, [both] the man that lay with the woman, and the woman: so shalt thou put away evil from Israel.

And David said unto Nathan, I have sinned against the LORD. And Nathan said unto David, The LORD also hath put away thy sin; thou shalt not die.

For this [is] an heinous crime; yea, it [is] an iniquity [to be punished by] the judges.

They say unto him, Master, this woman was taken in adultery, in the very act.
