This noun denotes one's bearing, conduct, or characteristic manner of presenting oneself. Titus 2:3 instructs older women to be reverent 'in demeanor'—their overall comportment should reflect holiness. The dative indicates the sphere in which reverence is shown. Classical usage extends from bodily/mental condition to weather to general state of affairs to personal deportment. The cross-linguistic witnesses vary (demeanor, comportamiento, Haltung/bearing), but converge on observable conduct or bearing. Paul envisions a lifestyle where godliness permeates visible behavior and characteristic manner.
