'Speak' in the Bible

He must hold firmly to the faithful message as it has been taught, so that he will be able to give exhortation in such healthy teaching and correct those who speak against it.

For there are many people who are rebellious, especially those who are converts from Judaism. They speak utter nonsense and deceive people.

But speak thou the things which become sound doctrine:

These things speak, and exhort, and rebuke with all authority. Let no man despise thee.

To speak evil of no man, to be no brawlers, but gentle, shewing all meekness unto all men.

This is a trustworthy statement; and concerning these things I want you to speak confidently, so that those who have believed God will be careful to engage in good deeds. These things are good and profitable for men.
