R’ Yechezkel Abramsky zt”l makes an interesting point in the beginning of this weeks parsha. In the case of Eshes Yifas Toar, the Torah basically gives in to the yetzer hara of man, and says since you can’t beat it, give in, but give in under the following conditions.
R’ Abramsky says that the above is the ONLY case where such action is permitted. He says there are many people who speak “hevel” who say that there are other such cases. Situations nowadays which one can go against the Torah because it is too difficult to keep the Torah.
The Torah HaKedosha disagrees. Yes the yetzer hara is tough, yes he is cunning and yes he offers the sweet taste of sin but he is ALWAYS beatable and the purpose of our being here is to improve ourselves by passing his tests.
