of good cheer

of good cheer

cheerful or optimistic. archaic
The exhortation to be of good cheer occurs in several passages of the New Testament in the Authorized Version of the Bible (for example in Matthew 9:2, John 16:33, and Acts 27:22). In Middle English, cheer had the meaning ‘face’. This sense of cheer is now obsolete, but the related senses of ‘countenance’ and ‘demeanour as reflected in the countenance’ survive in a number of phrases, including in good cheer and the archaic what cheer ? (how are you?).
