Exploring the Meaning of Sebomai in Greek

σέβομαι expresses being devout, and in these passages it is heard in disputes about worship, in descriptions of synagogue-adjacent hearers, and even in civic devotion to a goddess. It appears in the Gospels in critiques of vain worship, and in Acts as a recurring label for people marked out by their religious devotion.

Occurrences

“And in vain do they worship me, teaching as doctrine rules made by men.’ ” (Matthew 15:9)

Here σέβομαι stands inside a rebuke: worship is present, but it is “in vain.” The problem is not the outward activity of worship but the content shaping it—“teaching as doctrine rules made by men.” Devotion is depicted as misdirected when it is governed by merely human rules elevated to doctrinal status.

“But they worship me in vain, teaching as doctrines the commandments of men.’” (Mark 7:7)

This parallel wording again frames σέβομαι as an act that can be rendered empty (“in vain”) when paired with the wrong kind of instruction. The line turns on the contrast between “doctrines” and “the commandments of men,” presenting devotion as vulnerable to being hollowed out by the authority it follows.

“Now when the synagogue broke up, many of the Jews and of the devout proselytes followed Paul and Barnabas; who, speaking to them, urged them to continue in the grace of God.” (Acts 13:43)

σέβομαι here characterizes “proselytes” as “devout,” locating them among those who respond positively after a synagogue gathering. Their devotion is not described in the abstract; it is shown in action: they “followed Paul and Barnabas,” and they are the kind of hearers who can be urged “to continue in the grace of God.” Devotion, in this scene, marks an audience already disposed toward religious commitment and therefore engaged with apostolic exhortation.

“But the Jews stirred up the devout and prominent women and the chief men of the city, and stirred up a persecution against Paul and Barnabas, and threw them out of their borders.” (Acts 13:50)

In the same city context, σέβομαι again labels a group—“the devout and prominent women”—but the narrative role is different. Devout status here aligns with social prominence and civic influence, and that combination becomes a lever for public action: they are “stirred up” along with “the chief men of the city,” resulting in persecution and expulsion. Devotion is therefore presented as a real social force, capable of being rallied toward opposition as well as toward listening.

“A certain woman named Lydia, a seller of purple, of the city of Thyatira, one who worshiped God, heard us. The Lord opened her heart to listen to the things which were spoken by Paul.” (Acts 16:14)

σέβομαι identifies Lydia as “one who worshiped God,” setting her apart before anything is said about her response. Her devotion provides the backdrop for receptive hearing: she “heard us,” and then “The Lord opened her heart to listen.” The line presents devoutness as compatible with careful attention to spoken teaching, and it frames her listening as more than curiosity—an inward openness.

“Some of them were persuaded and joined Paul and Silas, of the devout Greeks a great multitude, and not a few of the chief women.” (Acts 17:4)

Here σέβομαι again functions as a descriptor of a distinct segment within a mixed audience: “the devout Greeks.” Their devotion does not keep them at the margins; they are among those who are “persuaded” and who “joined Paul and Silas,” and they are present in significant numbers (“a great multitude”). The verse links devoutness with a readiness to be convinced and to affiliate publicly.

“So he reasoned in the synagogue with the Jews and the devout persons, and in the marketplace every day with those who met him.” (Acts 17:17)

σέβομαι marks the group alongside “the Jews” within synagogue reasoning: “the devout persons.” The wording implies that devotion can describe people who are not simply defined by ethnicity but by religious posture. The scene also places synagogue discussion next to public daily discourse in the marketplace, suggesting that devout persons belong to the synagogue setting where sustained reasoning occurs.

“He departed there, and went into the house of a certain man named Justus, one who worshiped God, whose house was next door to the synagogue.” (Acts 18:7)

σέβομαι describes Justus as “one who worshiped God,” and the narrative highlights his location: “next door to the synagogue.” Devotion is tied to proximity and hospitality; the house of a worshiper becomes the new base of activity after departure “there.” The verse uses the label to signal that this household is religiously aligned in a way that makes it suitable for continued ministry.

saying, “This man persuades men to worship God contrary to the law.” (Acts 18:13)

Here σέβομαι is placed on the lips of accusers as the content of their charge. The issue is not whether people will be devout, but how they are being persuaded to be devout: “to worship God contrary to the law.” Devotion becomes the contested point at law and custom—an action that can be framed as legitimate or illegitimate depending on the norm appealed to.

“Not only is there danger that this our trade come into disrepute, but also that the temple of the great goddess Artemis will be counted as nothing and her majesty destroyed, whom all Asia and the world worships.” (Acts 19:27)

σέβομαι is applied broadly and publicly: “whom all Asia and the world worships.” Devotion is portrayed as widespread and socially stabilizing, tied to a “temple,” a “trade,” and the “majesty” of Artemis. The speaker fears both economic damage and religious diminishment, showing devotion as something that can anchor public reputation and perceived greatness.

Sense and Usage

Across these contexts, σέβομαι consistently functions as an indicator of devotion that can be assessed, described, and contested. In the Gospel sayings, devotion is evaluated by what shapes it: worship can be real activity and yet “in vain” when its content is the elevation of “rules made by men” or “the commandments of men” into doctrine. The word therefore sits naturally in a critique where the external act is not denied, but its emptiness is exposed by the teaching that accompanies it.

In Acts, the same devotion vocabulary becomes a social descriptor for identifiable people: “devout proselytes,” “devout and prominent women,” “devout Greeks,” and “devout persons.” These labels do not merely describe private piety; they help explain movement and reaction in public life. Devout hearers “followed” missionaries, were “persuaded,” and “joined” them; devout elites could also be “stirred up” into active opposition. The repeated pairing of devotion with synagogue settings (“when the synagogue broke up,” “reasoned in the synagogue,” “next door to the synagogue”) shows the word’s usefulness for naming those attached to worshiping communities and their practices, whether by regular participation, sympathy, or public identity.

σέβομαι also appears in the language of accusation and conflict. In Acts 18:13, devotion is framed as something that can be “persuaded,” and the dispute concerns whether that persuasion leads people into worship “contrary to the law.” The term thus serves as a focal point in contested religious space: devotion is not neutral; it belongs to norms and is judged against them. Finally, in Acts 19:27, devotion expands to the level of region-wide practice—“all Asia and the world”—and is closely tied to institutional and economic structures: temple honor, trade reputation, and the perceived “majesty” of a goddess. In that setting, σέβομαι carries the weight of collective religious allegiance that shapes a city’s identity and livelihoods.

Imagery

These passages place σέβομαι amid tangible scenes: synagogue gatherings breaking up with people following teachers, influential city figures being stirred into action, a household next door to a synagogue becoming a new center, and a famed temple whose honor is bound up with public acclaim. Devotion appears both as quiet attentiveness—“heard us,” “opened her heart to listen”—and as mass religious attachment—“all Asia and the world worships”—showing how the same word can sit comfortably in intimate listening and in sweeping public allegiance.
