Chillul Hashem

Chillul haShem (Hebrew: חילול השם‎ desecration of the Name), meaning desecration of the name of God, is a term used in Judaism for any act or behavior that casts shame or brings disrepute to belief in God, any aspect of the Torah's teachings, Jewish law, or the Jewish community.

Hebrew Bible

The source for this commandment is to be found in the Book of Leviticus: "And you shall not profane My holy name; but I will be hallowed among the children of Israel: I am the Lord who hallows you" - the Biblical Lev. 22:32 term meaning to bring dishonour or shame to God's name by an action or lack thereof.

In Judaism

Any behavior or action that disgraces, harms or shames God and his Law is regarded as desecration of God's name. The opposite concept, kiddush Hashem (sanctification of the name) means any action that brings honor, respect, and glory to God. It is often used to mean religious martyrdom. The obligation to refrain from desecration of the Name is one of the 613 commandments in rabbinical enumeration.
