'Reproach' in the Bible

namely, if any man is above reproach, the husband of one wife, having children who believe, not accused of dissipation or rebellion.

For the overseer must be above reproach as God’s steward, not self-willed, not quick-tempered, not addicted to wine, not pugnacious, not fond of sordid gain,

to be sensible, pure, makers of a home [where God is honored], good-natured, being subject to their own husbands, so that the word of God will not be dishonored.

Your message is to be sound beyond reproach, so that the opponent will be ashamed, having nothing bad to say about us.
