כְּתַב

כְּתַב

Definition

The noun כְּתַב (kᵉthab) refers to a written document, inscription, or decree. In its biblical usage, it specifically denotes an official, authoritative text, often a royal edict or legal record. For example, in Ezra 4:8 and 5:7, it describes the written accusation sent to King Artaxerxes against the Jews rebuilding Jerusalem. In Daniel 5:5, it famously refers to the mysterious 'writing on the wall' at Belshazzar's feast, a divine inscription of judgment. The word emphasizes the formal, established nature of the text, whether human or divine in origin.

Biblical Usage

This Aramaic word is used exclusively in the post-exilic books of Ezra and Daniel, reflecting the administrative and court language of the Persian period. It always appears in contexts of official documentation: the correspondence and decrees of Persian officials in Ezra (Ezra 4:8, 5:7, 5:10, 6:2) and the supernatural or royal decrees in Daniel (Daniel 5:5, 6:25, 7:1). Its usage patterns show it is not casual writing but carries legal and authoritative weight.

Etymology

כְּתַב is the Aramaic cognate of the Hebrew verb כָּתַב (kāthab, H3789), meaning 'to write.' It derives from a common Semitic root (k-t-b) associated with inscribing or recording. As a noun, it represents the product of the writing action—the 'thing written.' Its use in the Aramaic portions of the Old Testament highlights the linguistic shift during the exile and Persian rule.

Semantic Range

This word is theologically significant as it bridges human and divine communication. In Daniel, it is the medium for God's direct judgment (Daniel 5:5) and for promulgating Darius's decree about the God of Daniel (Daniel 6:25). It underscores the concept of God's word being 'inscribed' and made irrevocably authoritative, much like a royal decree. Understanding this term enriches reading by highlighting the weight and permanence God associates with His written messages, whether prophetic or providential through human rulers. In the Persian imperial context, a כְּתַב was not a private letter but a formal, often public, document with the full force of law. Once written and sealed, it was unchangeable (as seen in Esther and Daniel 6). This cultural understanding of irrevocable decrees frames the dramatic tension in stories like Daniel 6 and gives gravity to the 'writing on the wall' as a divine edict that cannot be appealed. סֵפֶר (sēpher, H5612) — A broader term for any written document, scroll, or book, less specific to decrees. דָּת (dāth, H1881) — Specifically refers to a law, decree, or royal statute, focusing more on the legal content than the physical document.
