“Do not desecrate My holy Name, but I shall be sanctified among the children of Israel.”

-Emor 22:32

This verse refers to the prohibition of chilul Hashem (desecration of G‑d’s Name) and the commandment of kidush Hashem (to sanctify G‑d’s Name).

There are conditions when a Jew must do everything, including self-sacrifice, for the observance of Torah, for thereby he sanctifies G‑d’s Name. Just as kidush Hashem is the supreme virtue, so, too, there is nothing worse than chilul Hashem.

The prophet Yechezkel refers to the fact of galut as a chilul Hashem: “When they entered the nations into which they came, they desecrated My holy Name when it was said of them ‘These are G‑d’s people yet they had to leave His land!’” (Ezekiel 36:20)

In turn, the redemption is a kidush Hashem, as it is said, “I shall sanctify My great Name which was desecrated among the nations, which you have profaned in their midst, and the nations will know that I am G‑d... when I will be sanctified in you before their eyes” (Ezekiel 36:23).

The very study and preoccupation with the laws of kidush Hashem in itself will end the chilul Hashem of the galut, and bring about the ultimate kidush Hashem signified by the Messianic redemption!
