PARSHA PEARLS

B'Kano Ess Kinasi
"In his (acting) zealous(ly) with my zeal"

Rashi explains this verse to mean that Pinchos (Phinehas) performed the zealous act that Hashem would have performed. Although Hashem can do anything effortlessly, it is praiseworthy to do something that Hashem would have done. This is the point that Rashi is making about Pinchos' action. Such actions are especially praiseworthy since they demonstrate one's love for Hashem. When one shows that he wishes to "help" Hashem - even though he realizes that Hashem does not actually need his help - he shows how much he loves Hashem and wants to fulfill his will.
(Darash Moshe)

STANDING TALL - ALONE

Tachas Asher Kinei LeElo-kav
"In the place (because) of that which he acted zealously for his g-d."

It is noteworthy that this verse refers to Hashem as "his (Pinchos') g-d", inferring that Pinchos had an exclusive relationship with Him. Since Hashem is the Master of the whole universe, He should have been referred to as the G-d of all. The fact that He is called "his G-d" indicates that Pinchos accepted the entire responsibility of defending Hashem's honor. He was unaffected by anyone else's inaction. Thus, he earned the honor that this verse accords him.
