Titus 2:9

Exhort servants to be obedient - The apostle refers to those who were slaves, and the property of their masters; even these are exhorted to be obedient ιδιοις δεσποταις , to their own despots, though they had no right over them on the ground of natural justice.

Please them well in all things - They were to endeavor to do this in all things, though they could not hope to succeed in every thing.

Not answering again - Μη αντιλεγοντας· Not contradicting or gainsaying. This is no part of a servant's duty; a servant is hired to do his master's work, and this his master has a right to appoint.
