Judges 16:17 - Clarke's commentary and critical notes on the Bible

That he told her all his heart, and said unto her, There hath not come a rasor upon mine head; for I have been a Nazarite unto God from my mother's womb: if I be shaven, then my strength will go from me, and I shall become weak, and be like any other man. If I be shaven, then my strength will go from me - The miraculous strength of Samson must not be supposed to reside either in his hair or in his muscles, but in that relation in which he stood to God as a Nazarite, such a person being bound by a solemn vow to walk in a strict conformity to the laws of his Maker. It was a part of the Nazarite's vow to permit no razor to pass on his head; and his long hair was the mark of his Nazirate, and of his vow to God. When Samson permitted his hair to be shorn off, he renounced and broke his Nazir vow; in consequence of which God abandoned him, and therefore we are told, in Judges 16:20, that the Lord was departed from him.
