The Nazirite Vow
A Nazirite, as described in the Book of Numbers, was an Israelite consecrated by a vow that imposed three principal obligations: abstaining from wine, strong drink, and grape products; refraining from cutting the hair of the head; and avoiding ritual impurity from contact with the dead. While most Nazirite vows were taken voluntarily for a fixed period, Samson belonged to a small group of figures set apart for life, his consecration established by a maternal vow before his birth. The biblical account links the keeping of this vow, and especially the uncut hair, to the strength by which he opposed the Philistines.
