Lifnei Iver

In Judaism, Lifnei Iver (Hebrew: לִפְנֵי עִוֵּר, "Before the Blind") is a way of referring to the concept of a stumbling block in rabbinical texts. The origin comes from the commandment, "וְלִפְנֵ֣י עִוֵּ֔ר לֹ֥א תִתֵּ֖ן מִכְשֹׁ֑ל (Before the blind, do not put a stumbling block)" (Leviticus 19:14).

The Hebrew term lifnei iver is one of the offenses which the Talmud argues to be punishable by excommunication in Judaism. The stumbling block as a distinct, and negative, concept is also established in Christian theology: in Catholicism it is known as creating scandal.
