ושם אמו, and the name of his mother, etc. Why was the name of this woman only mentioned here instead of at the time her existence was mentioned in verse 10 prior to the confrontation of her son with Moses? One may answer this in either one of two ways. 1) It reflects credit upon her seeing the Torah wrote: "they brought him to Moses, whereas the name of his mother was Shlomit." This implies that his mother was one of those who brought the blasphemer to Moses to be judged. 2) Mention of Shlomit at this stage reflects discredit upon her. Had it not been for the fact that others brought the blasphemer to Moses for judgment his mother could have remained anonymous. The general tenor of the story indicates that the blasphemer's mother could not overcome her feelings of pity for her son. The Torah teaches the lesson which we learned in Proverbs 12,10 that compassion for the wicked is actually an act of cruelty. The Torah discloses the name of the woman who had been foolish enough to display such feelings for her son the blasphemer. The fact that the Torah also reveals the name of her tribe is an indication that members of a tribe have a tendency to be protective of members of that tribe. This is why the Midrash we quoted earlier stated that when a person disgraces himself he also disgraces his tribe.
Or HaChaim
לא תחוס עינך, "do not display pity, etc." This is what Solomon taught us in Proverbs 12,10: "showing compassion to the wicked is cruelty." Contrary to the common belief that the display of pity is a virtue, the Torah teaches that this is not only not necessarily so, but it can even be a negative virtue. Perhaps the Torah had to warn us about this seeing that G'd blesses Israel with an abundance of children. We have also been taught in Sanhedrin 36 that fathers are apt to show more pity than men who have no children and that as a result men who have no children cannot be appointed to the Supreme Court as they lack a measure of that virtue. To make certain that pity would not be shown to the people whom G'd wants to destroy the Torah had to legislate this in our verse.
Rashi
You know Your servant. You have supplied me with all my needs as [it says] (Mishlei 12:10) "A righteous man knows his animal's being.15The verse refers to a righteous person but Rashi is drawing an analogy to Hashem’s knowing the needs of his servants."
