Sforno on Exodus 21:1/ספורנו על שמות כ״א:א׳

1ואלה המשפטים, in the previous paragraph the Torah spoke about the prohibition of coveting property belonging to someone else (20,13). This did not involve action; by contrast ואלה המשפטים, now the Torah speaks about laws governing the concrete nature of “אשר לרעך,” tangible matters belonging to your fellow man.

2אשר תשים לפניהם. These are not positive commandments and negative commandments which apply to every Jew, but are applicable only if the occasion arises. The matters under discussion need to be adjudicated only if and when such situations occur in someone’s life.
