"And I will be sanctified among the Children of Israel"Leviticus 22:32.

We are commanded to sanctify G‑d’s holy Name by publicly proclaiming our faith and religion. In the event that a tyrant attempts to coerce us to renounce our belief in G‑d, we are commanded to refuse to comply—even if the tyrant threatens to kill us. We may not even verbally deny our belief in G‑d, though in our hearts we remain true to Him.
