εὐδία

good weather

Definition

εὐδία refers specifically to fair or good weather, particularly clear, calm skies. In the New Testament, it is used only in Matthew 16:2, where Jesus speaks of people interpreting the appearance of the sky. The word denotes a settled, pleasant atmospheric condition, the opposite of stormy or threatening weather. It carries the straightforward sense of meteorological tranquility.

Biblical Usage

This word appears only once in the New Testament, in Matthew 16:2-3. Jesus uses it in a proverbial saying to critique the religious leaders' spiritual discernment: they can predict fair weather (εὐδία) by observing the red sky at evening, but cannot interpret the 'signs of the times.' Its usage is entirely literal, describing a natural phenomenon used for a spiritual analogy.

Etymology

Derived from the Greek adjective εὔδιος (eudios), meaning 'calm' or 'tranquil,' which itself comes from εὖ (eu, 'good, well') and Διός (Dios, the genitive of Zeus, god of the sky). Thus, its etymology points to the idea of a sky favorable or kindly disposed by Zeus, evolving into the general sense of clear, good weather.

Semantic Range

While the word itself is mundane, its single biblical use in Matthew 16:2-3 is theologically significant. Jesus employs this everyday observation about weather prediction as a sharp contrast to highlight the spiritual blindness of the Pharisees and Sadducees. Understanding εὐδία enriches the reading by emphasizing the irony: they were experts in reading natural signs (like fair weather) but utterly failed to recognize the divine signs and the Messiah standing before them. It underscores themes of spiritual perception and the urgency of recognizing God's work in the present moment.

In the ancient Mediterranean world, weather observation was crucial for agriculture, travel, and daily life. The ability to predict fair weather from a red sunset (as noted in Matthew 16:2) was a common piece of folk wisdom, similar to the modern adage 'Red sky at night, sailor's delight.' This cultural understanding made Jesus' analogy immediately accessible to his audience.

γαλήνη (galēnē, G1055) — specifically denotes a calm at sea, often translated 'calm' or 'tranquility,' whereas εὐδία is more general fair weather of the sky.
