Exploring the Meaning of Tessareskaidekatos in Greek

τεσσαρεσκαιδέκατος means “fourteenth” and appears in Acts 27 within the account of a ship driven through dangerous seas. In both occurrences it marks time with exactness, anchoring the narrative to a particular night and a particular day of waiting.

Root and Related Words

τεσσαρεσκαιδέκατος is connected with τέσσαρες (tessares), “four” (Strong’s G5064), καί (kai), “and” (Strong’s G2532), and δέκατος (dekatos), “tenth” (Strong’s G1182). The compound structure ties together the number four with ten by means of “and,” yielding a single ordinal expression.

Occurrences

“But when the fourteenth night had come, as we were driven back and forth in the Adriatic Sea, about midnight the sailors surmised that they were drawing near to some land.” (Acts 27:27)

Here τεσσαρεσκαιδέκατος fixes the scene on a specific night within a prolonged ordeal at sea. The narrative depicts continuous motion—“driven back and forth”—and the time marker “about midnight” heightens the sense of disorientation and danger. Calling it “the fourteenth night” frames the sailors’ perception (“surmised that they were drawing near to some land”) as something reached only after an extended, measurable period of being carried by wind and waves. The word functions as a hard boundary in the story: this is not merely “many nights” but a counted night that signals endurance up to that point and a potential turning point as land seems near.

“While the day was coming on, Paul begged them all to take some food, saying, “Today is the fourteenth day that you wait and continue fasting, having taken nothing.” (Acts 27:33)

In this second use, τεσσαρεσκαιδέκατος marks the day that matches the length of the crisis in bodily terms—waiting, fasting, and weakness. The timing is again precise: “While the day was coming on” sets a threshold moment between night and day, and Paul’s appeal is grounded in the duration the group has endured: “the fourteenth day that you wait and continue fasting.” The ordinal anchors Paul’s urging in a shared, countable experience; the speaker can point to a definite number of days as evidence of strain (“having taken nothing”) and as the immediate rationale for action (“begged them all to take some food”). The word thus supports the practical force of the plea by tying it to a clearly defined stretch of time.

Sense and Usage

Across these two contexts, τεσσαρεσκαιδέκατος operates as an ordinal used for narrative precision rather than as a mere statistic. In Acts 27:27 it is attached to “night,” and in Acts 27:33 it is attached to “day,” so the word participates in the story’s movement through the daily cycle—night marked by drifting and uncertainty, daybreak marked by urgent counsel and the need to eat. The effect is to portray duration as something tracked and counted within the crisis: the voyage’s danger and the crew’s deprivation are not vague impressions but realities measured in a defined sequence of nights and days.

The ordinal also shapes the reader’s sense of escalation. A “fourteenth” point in a sequence implies that the preceding time has accumulated; the situation has continued long enough to be numbered to that stage. In Acts 27, this counted duration is paired with concrete circumstances: the ship is “driven back and forth,” the setting is “the Adriatic Sea,” and the sailors “surmised” land was near; then, as daylight approaches, Paul speaks of waiting and fasting “having taken nothing.” Within these lines, τεσσαρεσκαιδέκατος helps bind environmental threat and human exhaustion into a single timeline, showing how sustained danger and sustained hunger converge at a definable moment.

Imagery

The word’s imagery in these passages is the imagery of time kept under pressure: a numbered night on a restless sea and a numbered day of waiting without food. By marking “the fourteenth night” and “the fourteenth day,” τεσσαρεσκαιδέκατος contributes a stark sense of accumulation—days and nights stacking up—within a scene of darkness, midnight guesswork, and the first light of daybreak when decisive action is urged.
