Learn More →ἀριστερός is the Greek word for “left,” used in the New Testament in concrete, spatial contrasts with “right.” It appears in Jesus’ teaching, in a request about seating “in your glory,” in the crucifixion scene, and in Paul’s imagery of “armor of righteousness.”

Root and Related Words
ἀριστερός is connected (in Strong’s) with the related word ariston (ἄριστον, Strong’s G712), glossed as “early meal.”

Occurrences
“But when you do merciful deeds, don’t let your left hand know what your right hand does,” (Matthew 6:3)
Here “left” is part of a paired contrast within the same body: “your left hand” is set against “your right hand.” The sentence depends on the bodily image of two hands acting in close proximity, yet treated as if they could be kept from sharing information. The force of ἀριστερός in this line is not abstract but physical: it locates one hand on one side, so that the image of concealment can be expressed sharply—one hand “knowing” and the other not. The word’s placement inside a proverb-like instruction makes “left” serve as a concrete marker in a vivid picture of discretion.

“They said to him, “Grant to us that we may sit, one at your right hand, and one at your left hand, in your glory.”” (Mark 10:37)
In this request, ἀριστερός helps define two positions flanking Jesus: “one at your right hand, and one at your left hand.” The word functions as a coordinate in a symmetrical arrangement, where the desired honor is expressed by nearness and placement. Because both sides are explicitly named, “left” is not a mere direction but part of a complete picture of paired seats around a central figure. The phrase “in your glory” frames these locations as prestigious, and ἀριστερός contributes to the idea that the petitioners want defined, recognized places—not simply to be present, but to be placed in a particular orientation relative to Jesus.
“When they came to the place that is called “The Skull”, they crucified him there with the criminals, one on the right and the other on the left.” (Luke 23:33)
Luke uses ἀριστερός to describe the layout of three crucifixions: Jesus “there with the criminals,” with one criminal located “on the right” and the other “on the left.” The word fixes one criminal’s position relative to Jesus, giving the scene a stark spatial clarity. Because the verse mentions “the place that is called “The Skull”” and then immediately gives the arrangement, “left” serves the narrative by anchoring the reader in what is happening “there,” at that location. The pairing “one on the right and the other on the left” frames Jesus between two others; ἀριστερός is one half of that framing, completing the description of how the criminals were situated.
“in the word of truth, in the power of God; by the armor of righteousness on the right hand and on the left,” (2 Corinthians 6:7)
Paul places ἀριστερός within an image of being equipped: “by the armor of righteousness on the right hand and on the left.” The phrase suggests coverage that extends to both sides; “left” here is not merely a direction but part of a totalizing pair—right side and left side together—used to communicate completeness in readiness. The expression is embedded among phrases that speak of divine enablement (“in the power of God”), and the spatial language contributes a bodily, almost tangible sense to “armor of righteousness,” as though righteousness is worn or borne in a way that attends to both hands and therefore to the full span of action.
Sense and Usage
Across these passages, ἀριστερός consistently marks the “left” side in deliberate contrast with “right.” The word’s meaning is simple, but its role is flexible: it can sharpen a teaching image (hands that “know” or do not know), describe sought-after placement (seating at Jesus’ side), establish the physical arrangement of a public event (the crucifixion scene), or extend an image of preparedness (armor on both sides).
The repeated pairing with “right” shows that “left” is most often used not in isolation but as a coordinate within a balanced set. In Matthew 6:3, the contrast is internal to a single person—two hands—so ἀριστερός works at the scale of personal action and discretion. In Mark 10:37, the contrast is relational and social: “left” indicates one of the honored flanking positions around a central figure “in your glory.” In Luke 23:33, the contrast is narrative and spatial: the “left” side identifies one of the criminals, and the pair of directions places Jesus between them, giving the scene an ordered, almost diagram-like arrangement. In 2 Corinthians 6:7, the contrast is metaphorical but still bodily: “right hand and … left” speaks of equipment that attends to both sides, making the imagery of “armor” feel comprehensive rather than partial.
In each case, ἀριστερός does its work by locating something or someone in relation to a center—either the person’s own body (left hand versus right hand) or a focal person in the scene (those seated by Jesus; those crucified beside him). Even when the context is figurative (“armor of righteousness”), the wording remains anchored in physical orientation, so that “left” keeps its concrete spatial force while helping convey broader points about conduct, honor, suffering, or readiness.
Imagery
The passages that use ἀριστερός present “left” as a way of making invisible matters visible through orientation: discretion is pictured through two hands (Matthew 6:3), ambition through two seats beside a central figure (Mark 10:37), suffering through two criminals positioned around Jesus (Luke 23:33), and endurance through armor spanning both sides (2 Corinthians 6:7). In each scene, “left” helps form a complete frame with “right,” giving the reader a clear spatial map for what the text is communicating.
