Why does the Torah insert the La'av of "cutting oneself over a deceased person here?
Rashi: Because, like the La'avin concerning sorcery, it was practiced by Amori'im. 1
The question remains however, why the Pasuk did not then insert it before the La'avin in Pasuk 27?
What is the definition of "Kesoves Ka'aka"?
Why does the Torah insert "Ani Hashem" here?
Rashi (in Shit ha'Shirim, 5:16): It teaches us that Hashem will reward those who desist from going in the ways of the Emori'im and transgressing these La'avin. 1
Rashi, Ibid.: 'Is there anything sweeter to the palate than the fact that Hashem promises reward for simply not cutting oneself up?'.
