Why did Eisav Harasha send his son Elifaz to kill Yaakov? Why not chase
after Yaakov himself? Eisav knew that if he were to kill Yaakov, it would
cause great anguish to Yitzchak. This would go against his mitzvah of
kibbud av v’em.

Why did Eisav send Elifaz and not hire some mercenaries to assassinate
Yaakov? Wasn’t Eisav worried that Yaakov would defend himself? Eisav
put Elifaz in great danger by sending him on his mission.

In his hatred for Yaakov, Eisav wanted to kill him even if it meant putting
his son’s life in mortal danger. He also overlooked the anguish his father
would have felt over Yaakov’s death. Eisav was assured that his son
would do everything humanly possible to expedite his father’s wishes and
fulfill the mitzvah of kibbud av v’em.
