פּירוש אויף שמות 21:14

וכי יזד AND IF A MAN ACT INTENTIONALLY — Why is this stated at all (since v. 13 expressly provides a place for the murderer only if he does not lie in wait)? Since it is said, (v. 12) “Whosoever smiteth a man [so that he die shall be put to death]”, I might infer that this is so even if the victim is a heathen, and that there it included even a physician who kills a person as a result of his treatment, and a court-officer who kills a man when inflicting on him the forty lashes, and a father who beats and thereby kills his son, and a teacher who chastises his pupil and thereby kills him, and one who kills in error (שוגג, i. e. one who intended to kill a certain person but missed the mark and killed another instead — נתכוין להרוג את זה והרג את זה)! Scripture therefore states here: “if a man acts intentionally (יזיד)” — but not in error (שוגג); “against his fellowman (רעהו)” — but not against a heathen; “to slay with guile (בערמה)” — thus excluding the court-officer, the physician, and one who chastises his son or his pupil for all these though acting intentionally do not do so with guile (cf. Mekhilta).

מעם מזבחי, even when the murderer has taken refuge near My altar; all the more so when he escaped to one of these cities of refuge.

מעם מזבחי, even though at that time when no cities of refuge existed yet the entire camp of the Levites, and not only the immediate area of the altar served as such a place of refuge.

מעם מזבחי תקחנו למות THOU SHALT TAKE HIM FROM MY ALTAR, THAT HE MAY DIE — even if he is a priest and stands at the altar intending to officiate thou shalt take him away that he die (cf. Mekhilta; Yoma 85a).
