Ἰσαάκ
Isaák
G2464 noun
SILEX Entry
Definition
Isaak; proper name referring specifically to the son of Abraham and Sarah in Israelite tradition. In Greek usage, Ἰσαάκ is an untranslated phonetic rendering of the Hebrew personal name Yitzchaq (יִצְחָק), appearing primarily as a personal name in genealogical, narrative, and theological contexts. Unlike Greek-origin names, Ἰσαάκ does not acquire additional lexical senses in Greek usage, consistently designating the same historical figure.
Semantic Range
proper name; refers uniquely to the biblical figure Isaac; sometimes used figuratively as an ancestor or type, but semantically points to the individual Isaac in genealogical and literary contexts
Root / Etymology
Transliterated from Hebrew יִצְחָק (Yitzchaq), meaning 'he will laugh' or 'he laughs,' from the Hebrew root צחק (tsḥq, 'to laugh').
Historical & Contextual Notes
The name Ἰσαάκ (Isaák) enters Greek via transliteration from Hebrew rather than through Greek morphological processes. In all extant biblical Greek sources (Septuagint, New Testament, intertestamental texts), the form remains unchanged, not inflected according to Greek paradigms, reflecting its foreign (Hebrew) origin. The use of Ἰσαάκ is confined to reference to the patriarch, son of Abraham and Sarah, significant in ancestral lists and covenantal narratives. Unlike many Hebrew personal names that were adapted to Greek grammar (e.g., with an -ος ending), Ἰσαάκ retains the Hebrew final -κ, even when used syntactically as a Greek accusative or genitive. The Septuagint and later Jewish-Greek and Christian-Greek texts maintain this form. Standard English translations use “Isaac,” which follows the transliteration tradition but does not convey the literal Hebrew meaning ('he laughs'). Use of this name in the New Testament (e.g., Romans 9:7, Hebrews 11:9) presumes familiarity with the Israelite ancestral traditions.
Original Strong's Gloss (1890)
of Hebrew origin (יִצְחָק); Isaac (i.e. Jitschak), the son of Abraham:--Isaac.
