Lateran IV’s dress-separation decree cited Moses loosely, not a specific biblical text.

Evidence

The reference to Moses does not, it appears, refer to any specific biblical passage, but rather to widespread Jewish practice of distinguishing themselves from non- Jews through dress. — John V. Tolan, Saracens, 1837

Categorization

• XREF: Connects to the ‘Complaints About Immodesty Go Way Back’ article — sumptuary/dress norms as identity and political signaling, here aimed specifically at Jews and Saracens in Lateran IV canon 68.
• ADDENDUM: Directly relevant to ‘Complaints About Immodesty Go Way Back’: this is a canonical, church-imposed dress-separation mandate for Jews and Muslims, an institutional counterpart to the moral panics in that article.
