Orthodox Christian piety begins in the Holy Tradition of the Old Testament. Our relationship to the Lord God, holiness, worship, and morality was formed in the ancient times of the Bible. At the time of the foundation of the priesthood the Lord gave the following commandments to the priests during periods of mourning, And ye shall not shave your head for the dead [a pagan practice] with a baldness on the top; and they shall not shave their beard... (Lev. 21:5), and to all men in general, Ye shall not make a round cutting of the hair of your head, nor disfigure your beard (Lev. 19:27). The significance of these commandments is to illustrate that the clergy are to devote themselves completely to serving the Lord. Laymen as well are called to a similar service though without the priestly functions. This out ward appearance as a commandment was repeated in the law given to the Nazarene, a razor shall not come upon his head, until the days be fulfilled which he vowed to the Lord: he shall be holy, cherishing the long hair of the head all the days of his vow to the Lord... (Numbers 6:5-6).
