Learn More →ὑγιαίνω means “be healthy” and appears in narratives of bodily well-being and in pastoral exhortations about teaching and faith. In the Gospels it describes persons in ordinary life—those not needing a physician, a healed servant, and a restored son—while in the letters it is paired with “doctrine,” “words,” and “faith,” extending the imagery of health to what is taught and embraced.

Occurrences
Luke 5:31 — Jesus answered them, “Those who are healthy have no need for a physician, but those who are sick do.
Here ὑγιαίνω marks the condition of people who are not patients: the “healthy” are contrasted with “the sick,” and the contrast drives the point about who “need[s]” a physician. The word contributes a plain, physical category in the illustration—health as the state in which medical intervention is unnecessary.

Luke 7:10 — Those who were sent, returning to the house, found that the servant who had been sick was well.
In this scene the word describes the outcome discovered upon returning “to the house”: a servant previously “sick” is now “well.” ὑγιαίνω supplies the concrete result that answers the earlier condition, emphasizing a change from illness to health that can be verified by those who arrive and see for themselves.
Luke 15:27 — He said to him, ‘Your brother has come, and your father has killed the fattened calf, because he has received him back safe and healthy.’
Within the household celebration, ὑγιαίνω characterizes the returning brother’s condition as part of the reason for rejoicing: the father “has received him back safe and healthy.” The word stands alongside “safe,” making health one component of the restored state that warrants the feast and frames the father’s reception as complete and positive.
1 Timothy 1:10 — for the sexually immoral, for homosexuals, for slave-traders, for liars, for perjurers, and for any other thing contrary to the sound doctrine,
Here ὑγιαίνω is attached to “doctrine,” presenting teaching as something that can be “sound.” The list of behaviors is said to be “contrary to the sound doctrine,” so the word functions as a standard: there is a kind of doctrine that is healthy, and certain practices stand opposed to it.
1 Timothy 6:3 — If anyone teaches a different doctrine, and doesn’t consent to sound words, the words of our Lord Jesus Christ, and to the doctrine which is according to godliness,
In this warning, ὑγιαίνω qualifies “words,” specifically “the words of our Lord Jesus Christ,” and it sits in a cluster of terms about teaching: “different doctrine,” “sound words,” and “the doctrine which is according to godliness.” The word’s contribution is to mark a set of words as healthy ones to which a teacher must “consent,” contrasting with a teacher who introduces “different” instruction.
2 Timothy 1:13 — Hold the pattern of sound words which you have heard from me, in faith and love which is in Christ Jesus.
Here ὑγιαίνω again modifies “words,” and the emphasis falls on retention: “Hold the pattern of sound words.” The word supplies the quality of the “pattern” to be held—healthy words received from the speaker—while the verse links that holding to “faith and love,” situating healthy speech within a lived, relational posture.
2 Timothy 4:3 — For the time will come when they will not listen to the sound doctrine, but having itching ears, will heap up for themselves teachers after their own lusts,
In this prediction, ὑγιαίνω describes “doctrine” that people “will not listen to.” The word sets up the tragedy: a doctrine characterized as healthy is refused, while the alternative is the accumulation of teachers shaped by “itching ears” and “their own lusts.” Healthy teaching is portrayed as something that can be rejected in favor of what caters to desire.
Titus 1:9 — holding to the faithful word which is according to the teaching, that he may be able to exhort in the sound doctrine, and to convict those who contradict him.
In the description of a leader’s capacities, ὑγιαίνω is tied to “doctrine” used for both encouragement and correction: “exhort in the sound doctrine, and to convict those who contradict him.” The word marks the doctrine as healthy for the community, able to build up through exhortation and also to expose contradiction.
Titus 1:13 — This testimony is true. For this cause, reprove them sharply, that they may be sound in the faith,
Here ὑγιαίνω shifts from qualifying teaching to qualifying persons: the goal of sharp reproof is “that they may be sound in the faith.” The word frames the desired outcome as health within “the faith,” presenting correction as a means toward a healthy condition, not merely punishment.
Titus 2:1 — But say the things which fit sound doctrine,
In this instruction about speech, ὑγιαίνω again modifies “doctrine,” and the imperative is practical: “say the things which fit sound doctrine.” The word contributes a criterion for what should be spoken—speech is to be shaped so that it matches and suits teaching characterized as healthy.
Titus 2:2 — that older men should be temperate, sensible, sober minded, sound in faith, in love, and in perseverance:
Here ὑγιαίνω describes older men as “sound” in several spheres: “in faith, in love, and in perseverance.” Health is portrayed as a stable, dependable condition expressed across enduring commitments and attitudes, not restricted to one aspect of life.
3 John 1:2 — Beloved, I pray that you may prosper in all things and be healthy, even as your soul prospers.
In this prayer-wish, ὑγιαίνω returns to bodily well-being, set alongside broad flourishing: “prosper in all things and be healthy.” The phrase “even as your soul prospers” places physical health in parallel with inner prosperity, presenting health as one dimension of overall thriving for the beloved recipient.

Sense and Usage
Across these passages ὑγιαίνω consistently names health as a positive condition, but the texts deploy that condition in two distinct, complementary arenas. In Luke’s narratives, health is tangible and observable: the healthy do not seek a physician (Luke 5:31), a once-sick servant is found well at home (Luke 7:10), and a returned family member is received “safe and healthy” (Luke 15:27). In each case, being healthy functions as a boundary marker between need and lack of need, between former sickness and present wellness, and between loss and restored life within a household.
In the Pastoral Epistles and in Titus especially, the same word is applied to “doctrine,” “words,” and “faith.” This usage draws on the ordinary idea of health to characterize teaching that is fit to be received, held, spoken, and used for exhortation and conviction (1 Timothy 1:10; 1 Timothy 6:3; 2 Timothy 1:13; Titus 1:9; Titus 2:1). The health metaphor also reaches persons: communities and individuals can be “sound in the faith” as a result of reproof (Titus 1:13), and older men are to be “sound in faith, in love, and in perseverance” (Titus 2:2). The letters thus treat health as a quality that can describe not only bodies but also the integrity and stability of what is taught and trusted.
Several passages sharpen the contrast that makes the health imagery vivid. Healthy doctrine is opposed by actions “contrary” to it (1 Timothy 1:10). Healthy words demand consent and are linked explicitly to “the words of our Lord Jesus Christ” (1 Timothy 6:3). Healthy doctrine can be refused when hearers prefer teachers that suit “their own lusts” (2 Timothy 4:3). In these ways, ὑγιαίνω becomes a way to speak about teaching and faith in terms of their capacity to sustain communal life, resist contradiction, and endure over time.
Imagery
The imagery connected with ὑγιαίνω moves easily from the sickbed to the meeting of the church. Luke places the word in settings where health is noticed in ordinary relationships—physician and patient (Luke 5:31), master and servant (Luke 7:10), father and son within a celebratory meal (Luke 15:27). The letters then treat healthy teaching as something to consent to, hold, listen to, and speak, as though doctrine and words can either sustain a community’s life or fail to do so (1 Timothy 6:3; 2 Timothy 1:13; 2 Timothy 4:3; Titus 2:1). Finally, 3 John joins outward well-being to inner prosperity in a single prayer, keeping bodily health and the health of the soul side by side without collapsing them into the same thing (3 John 1:2).
