Historical & Contextual Notes

τεσσαρακονταετής is a non-comparative numeral adjective rare in classical Greek but found in Hellenistic and Koine sources, including the New Testament (Acts 4:22, 13:21). It strictly designates a duration of forty years, either as the age of a person or the span of time since an event. Its usage is straightforward and descriptive, lacking broader metaphorical or idiomatic senses. Unlike some age-related adjectives in Greek that can acquire figurative meaning (e.g., ἡβῶν for maturity), τεσσαρακονταετής denotes literal chronology. In Septuagint and New Testament contexts, it typically marks a significant chronological milestone or the fulfillment of a period (e.g., the age of an individual or the span of a reign). English translations usually render it as 'forty years old' or 'of forty years,' which accurately represent its meaning; there is little evidence for significant semantic change between the Septuagint and New Testament. No distinct theological or symbolic use emerges in the primary sources.

Original Strong's Gloss (1890)

from τεσσαράκοντα and ἔτος; of forty years of age:--(+ full, of) forty years (old).
