τέταρτος marks something as the fourth in an ordered series, whether a time-period, a day-count, a creature, a seal, an angel, a bowl, or a foundation stone. In the New Testament it appears in Gospel narrative, in Acts, and repeatedly in Revelation where sequences are carefully numbered.
Occurrences
“In the fourth watch of the night, Jesus came to them, walking on the sea.” (Matthew 14:25)
Here τέταρτος fixes the moment within the night by pointing to the fourth “watch.” The word contributes a precise placement in a recognized sequence of night divisions, setting the scene at a late stage of the night as Jesus approaches “walking on the sea.” The narrative effect is to anchor the action in a specific segment rather than leaving the timing vague.
“Seeing them distressed in rowing, for the wind was contrary to them, about the fourth watch of the night he came to them, walking on the sea, and he would have passed by them,” (Mark 6:48)
Again τέταρτος identifies the relevant watch of the night, but Mark adds “about,” giving an approximate placement within that fourth period. The word helps order the unfolding scene: the disciples’ struggle “for the wind was contrary” has continued into the late-night sequence, and Jesus’ arrival “walking on the sea” is tied to that particular watch, intensifying the sense of prolonged strain before rescue.
“Cornelius said, “Four days ago, I was fasting until this hour, and at the ninth hour, I prayed in my house, and behold, a man stood before me in bright clothing,” (Acts 10:30)
In Cornelius’s recounting, τέταρτος structures the testimony by giving a day-count—“Four days ago”—from the present moment back to the initiating event. The word contributes chronological organization: Cornelius links his fasting “until this hour” and his prayer “at the ninth hour” to a specific point four days earlier when “a man stood before me in bright clothing.” The sequence makes his story measurable and anchored in time rather than merely remembered as an undated experience.
“The first creature was like a lion, and the second creature like a calf, and the third creature had a face like a man, and the fourth was like a flying eagle.” (Revelation 4:7)
τέταρτος closes a fourfold description by identifying the final creature in a set: “the fourth was like a flying eagle.” The word’s role is to complete the ordered list—first, second, third, fourth—so the reader understands the eagle-likeness as belonging to the last member of a defined quartet rather than as an additional, uncounted figure.
“When he opened the fourth seal, I heard the fourth living creature saying, “Come and see!”” (Revelation 6:7)
This verse uses τέταρτος twice to coordinate two parallel sequences. “The fourth seal” places the action at a particular stage in a numbered series of openings, and “the fourth living creature” aligns the speaking creature with its own ordered set. The word functions like a hinge between the sequences: at the opening of the fourth seal, the fourth living creature is the one heard saying, “Come and see!”
“And behold, a pale horse, and the name of he who sat on it was Death. Hades followed with him. Authority over one fourth of the earth, to kill with the sword, with famine, with death, and by the wild animals of the earth was given to him.” (Revelation 6:8)
Here τέταρτος appears in a fractional expression: “one fourth of the earth.” The word contributes a measured scope to the authority granted—large, yet explicitly limited by a fourth-part boundary. The verse then specifies the kinds of killing within that allotted fraction: “with the sword, with famine, with death, and by the wild animals of the earth.” τέταρτος thus helps communicate proportional impact, assigning the devastation a quantified reach.
“The fourth angel sounded, and one third of the sun was struck, and one third of the moon, and one third of the stars; so that one third of them would be darkened, and the day wouldn’t shine for one third of it, and the night in the same way.” (Revelation 8:12)
τέταρτος marks the angel as the fourth in a sequence of trumpet blasts: “The fourth angel sounded.” The verse’s effects are then described with repeated “one third” language, but τέταρτος is what locates these cosmic strikes within the progression of trumpet-soundings. It tells the reader that this particular darkening belongs to the fourth stage, not an isolated event.
“The fourth poured out his bowl on the sun, and it was given to him to scorch men with fire.” (Revelation 16:8)
In the bowl sequence, τέταρτος identifies which figure acts: “The fourth poured out his bowl on the sun.” The word contributes the position within an ordered series of pourings, and it ties that ordered step to a specific target (“on the sun”) and a specific outcome (“to scorch men with fire”). The numbering underscores that the scorching is associated with a particular phase in the unfolding judgments.
“The foundations of the city’s wall were adorned with all kinds of precious stones. The first foundation was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;” (Revelation 21:19)
τέταρτος labels the emerald as belonging to the fourth position among the foundations: “the fourth, emerald.” The word serves an inventory function within a decorative, architectural catalogue. By placing emerald in the fourth slot of the list (after jasper, sapphire, and chalcedony), τέταρτος contributes order and clarity to the description of the city wall’s foundations.
Sense and Usage
Across these passages, τέταρτος consistently works as an ordinal marker that makes sequences readable and events locatable. In the Gospels it anchors narrative time by referencing the “fourth watch of the night,” turning an otherwise general “night” setting into a specific segment within a known order; this makes the timing of Jesus’ approach (“walking on the sea”) part of the story’s structure, not mere background.
In Acts 10:30, the word shifts from a night division to a day-count, creating a timeline that connects fasting, prayer, and a visionary encounter. By setting the initial moment “Four days ago,” Cornelius frames his experience as a coherent chain of time-marked actions (“until this hour,” “at the ninth hour”) leading to the appearance of “a man… in bright clothing.” The ordinal idea supports reliability and sequencing in testimony: the events belong to a measurable span.
Revelation uses τέταρτος as part of a larger compositional strategy: vision-reporting often unfolds in numbered sets, and the ordinal functions like a pointer within those sets. In 4:7 it completes a fourfold portrait of living creatures, where the fourth closes the set and gives the final comparison (“like a flying eagle”). In 6:7 τέταρτος aligns two streams of numbering (seal and living creature), showing how the vision is interlocked: a particular opening corresponds to a particular voice. In 8:12 and 16:8 the word identifies which angel or which bowl-bearer is acting, so the reader can track the progression without confusion.
Revelation 6:8 shows a related but distinct usage: τέταρτος helps express a fraction (“one fourth of the earth”). Even here, the ordinal logic remains—one part out of four—so the word supplies a way to quantify extent. This proportional framing does interpretive work in the verse itself: authority is real and terrifying, but it is also described with a stated limit.
Finally, in 21:19 τέταρτος belongs to a carefully ordered catalogue of precious stones. The word helps the description read like a guided tour along successive foundations. The effect is not merely decorative; the enumeration communicates arrangement, suggesting that the foundations can be thought of in discrete, countable positions, each with its own adornment.
Imagery
Though τέταρτος is a simple ordinal, the scenes it marks are vivid: a late-night sea crossing (“the fourth watch of the night”), a counted interval of days leading to a luminous visitation (“Four days ago… a man stood before me in bright clothing”), and the layered sequences of Revelation where the “fourth” step can bring a new creature’s likeness, a voiced summons, cosmic dimming, scorching heat, or a named gemstone foundation. The word’s imagery is therefore indirect: it does not paint the scene by itself, but it places each image at a definite position in an ordered unfolding.
