A greeting which might be given in person, orally (Luke 1:29,41,44), or in writing, usually at the close of a letter (1 Corinthians 16:21; Colossians 4:18; 2 Thessalonians 3:17; compare use of chairein, "greeting," "joy" in James 1:1). The Pharisaic Jews loved salutations in public places (Matthew 23:7; Mark 12:38, the King James Version "greeting," the Revised Version (British and American) "salutation"; Luke 11:43; 20:46). Often these salutations were very elaborate, involving much time in prostrations, embracings, etc. When Jesus therefore sent out the Seventy, He forbade salutation by the way (Luke 10:4), though He ordinarily encouraged proper civilities of this sort (Matthew 5:47; 10:12).
