Why does the Torah intermix the subjects of the blasphemer and the laws of damages? In fact, why does the Torah mention this subject here at all? It appears to have no connection to either the preceding discussion ("lehem ha-panim" – the showbread) or to the following one (shemitta).

Through an examination of the chiastic structure of the parasha as well as the parallel between the episode of the man who cursed and the beginning of Moshe's mission, we can understand the placement of this story in its context.
