קַיִן
Kajin, the name of the first child, also of a place in Palestine, and of an Oriental tribe
Definition
The Hebrew word קַיִן (Qayin) is a proper noun with three primary referents in the Old Testament. First and foremost, it is the name of Cain, the firstborn son of Adam and Eve, whose story of fratricide and exile is central to Genesis 4. Second, it refers to a geographical location, the 'land of Nod, east of Eden' where Cain settled (Genesis 4:16). Third, it denotes the Kenite tribe, a group of metalworkers often associated with the Midianites, who later appear in Israel's history, sometimes as allies (e.g., Judges 4:11).
Biblical Usage
The word is used 15 times, predominantly in Genesis 4 (11 times) to narrate the story of Cain. The remaining four uses refer to the Kenite tribe or people, appearing in Numbers 24:21-22, Judges 4:11, and 1 Samuel 15:6. The usage shifts from a personal name in Genesis to an ethnic designation in the historical and prophetic books, indicating a perceived genealogical or cultural link to the biblical figure.
Etymology
The name קַיִן (Qayin) is identical to the common noun קַיִן (H7013), meaning 'spear' or 'smith,' linking to metalworking. The biblical text itself offers a popular etymology, punning on the verb קָנָה (qānâ, H7069), 'to acquire,' as Eve declares in Genesis 4:1, 'I have acquired a man with the help of the LORD.' This wordplay connects the name to themes of possession and creation.
Semantic Range
Cain is a foundational figure for understanding the devastating progression of sin after the Fall, illustrating jealousy, failed worship, murder, and God's justice tempered with mercy (the protective mark in Genesis 4:15). His name and story introduce themes of bloodguilt, exile, and the hope for divine protection even for the guilty. The connection to the Kenites also shows how God works through and with groups outside the direct Abrahamic lineage.
The association of the name with 'smith' reflects the ancient Near Eastern cultural memory of Cain's descendant, Tubal-cain, as 'the forger of all instruments of bronze and iron' (Genesis 4:22). The Kenites were known as itinerant metalworkers and smiths, a vital and often separate social class. The biblical narrative may preserve an etiological tradition explaining the origin of this tribe through the figure of Cain.
There are no direct synonyms for this proper name. For the associated concept of acquisition, see: קָנָה (qānâ, H7069) — the verb 'to acquire' or 'get,' used in the wordplay for Cain's name.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
