2 Corinthians 13:12

An holy kiss. In ancient times, and in various parts of the world today, this is a cordial form of greeting. Such a kiss was given on the cheek, the forehead, the hands, or even the feet, but never on the lips, men thus greeting men and women greeting women. The custom originated in OT times (Gen. 29:13). It expressed affection (Gen. 27:26, 27; 1 Sam. 20:41), reconciliation (Gen. 45:15), farewell (Ruth 1:9, 14; 1 Kings 19:20), and homage (1 Sam. 10:1). According to Justin Martyr it was commonly used in connection with the observance of the Lord’s Supper (First Apology 65). It came into general use among early Christians as a token of peace, good will, and reconciliation (Rom. 16:16; 1 Cor. 16:20; 1 Thess. 5:26).
