'Declare' in the Bible

each one’s work will be clearly shown [for what it is]; for the day [of judgment] will disclose it, because it is to be revealed with fire, and the fire will test the quality and character and worth of each person’s work.

But I say to the unmarried and to the widows, [that as a practical matter] it is good if they remain [single and entirely devoted to the Lord] as I am.

To the rest I declare—I, not the Lord [since Jesus did not discuss this]—that if any [believing] brother has a wife who does not believe [in Christ], and she consents to live with him, he must not leave her.
