What do we learn from "v'Ad Ishah Zonah Ad Kikar Lechem"?
Rashi: It brings one to poverty, and lacking all good.
Malbim: You will come to the point of [not having even] a loaf - you will lose your wealth and income.
What is the meaning of "Nefesh Yekarah Tatzud"?
Sotah 4b: Anyone who has Bi'ah with a married woman, even if he learned Torah, which "Yekarah Hi mi'Peninim (3:15)", i.e. dearer than the Kohen Gadol, who enters Lifnai v'Lifnim (the innermost part of the Mikdash), she snares him to judgment in Gehinom.
Rashi: A Nefesh that was dear beforehand, she comes and traps it to Gehinom.
Malbim: She traps the Nefesh itself, even though it is Yakar (dear) and elevated like a Navi or officer.
