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?).
