John Calvin Commentary Titus 2:3

"that aged women likewise be reverent in demeanor, not slanderers nor enslaved to much wine, teachers of that which is good;" — Titus 2:3 (ASV)

That aged women in like manner We very often see that older women either continue to dress with the frivolity of youth, or have something superstitious in their apparel, and seldom achieve the proper balance. Paul wished to guard against both extremes by instructing them to follow a way of life that is consistent with both outward decorum and religious devotion; or, to put it more simply, to show by their very dress that they are holy and godly women.

He next corrects two other vices to which they are often prone, when he forbids them to be slanderers and slaves to much wine. Talkativeness is a disease of women, and it is increased by old age. To this is added, that women never consider themselves eloquent enough unless they engage in idle talk and slander—unless they attack the character of everyone. The consequence is that older women, by their slanderous talkativeness, like a lighted torch, frequently set many houses on fire. Many are also given to drinking, so that, forgetting modesty and seriousness, they indulge in improper, unrestrained behavior.
