Paul continues giving Titus reasons to preach God's word, and explains how the older men, older women, young men, and slaves or servants should live as believers.
Paul implies what is in contrast. Alternate translation: "But you, Titus, in contrast with the false teachers, be sure to say those things that fit" (See: [[rc://en/ta/man/jit/figs-explicit]])
The word "healthy" here is a dead metaphor for true, trustworthy, and morally good. See how you translated "healthy" in [Titus 1:10](../01/10.md). Alternate translation: "trustworthy instruction" (See: [[rc://en/ta/man/jit/figs-metaphordead]])
