ἀτμίς

breath, steam, vapor

Definition

ἀτμίς refers to a fine, mist-like vapor or breath, something transient and insubstantial. In the New Testament, it is used metaphorically to describe the fleeting, ephemeral nature of human life, as seen in James 4:14, where life is compared to a 'vapor' that appears for a little while and then vanishes. In Acts 2:19, it appears in a quotation from the prophet Joel, describing 'vapor of smoke' as a portentous sign in the heavens, part of the dramatic cosmic imagery of the last days. Thus, the word carries both a literal sense of a visible mist or exhalation and a powerful figurative sense of transience.

Biblical Usage

This word is used only twice in the New Testament, in two distinct contexts. In Acts 2:19, it is used in a prophetic, apocalyptic context within Peter's Pentecost sermon, quoting Joel 2:30 (LXX 3:3) to describe 'vapor of smoke' as a celestial sign. In James 4:14, it is used in a wisdom context to make a philosophical and moral point about the uncertainty and brevity of human life. There is no pattern of common daily usage; both instances are highly rhetorical and metaphorical.

Etymology

Derived from the verb ἀτμίζω (atmizō), meaning 'to smoke' or 'to emit vapor.' It is related to the concept of breathing or exhalation. The word does not come from ἀ- (a negative prefix) plus 'tmis'; that is an older, now generally rejected etymology. Its core idea is that of a fine, dispersed substance like breath, steam, or mist.

Semantic Range

ἀτμίς is theologically significant for its contribution to the biblical theme of human mortality and divine sovereignty. In James 4:14, it provides a stark metaphor for the brevity and uncertainty of life, grounding the epistle's call for humility and dependence on God's will. Understanding this Greek term enriches the reading of James by emphasizing that life is not merely 'short' but insubstantial and fleeting, like a wisp of steam. This reinforces the urgency of living righteously. Its use in Acts 2:19 connects the Pentecost event to Old Testament prophecy, showing the continuity of God's revelation through dramatic signs.

In the ancient Greco-Roman world, vapor or mist (ἀτμίς) was a common natural observation used in philosophy and poetry to symbolize impermanence and illusion. This cultural understanding makes James's metaphor immediately resonant to his original audience. The image in Acts of 'vapor of smoke' would evoke the ominous, portentous signs familiar from both Jewish apocalyptic literature and broader ancient omen traditions.

πνεῦμα (pneuma, G4151) — spirit, wind, breath; a more substantial, often powerful breath or spirit. καπνός (kapnos, G2586) — smoke; a thicker, more opaque vapor, often from burning.
