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.

That he told her all his heart,.... All that was in his heart concerning this affair, all that he knew relating to it; he had told her something before, or at least what came nearer to the truth of the matter, when he directed her to the weaving of his locks into the web; but now he told her all, which is as follows:

and said unto her, there hath not come a razor upon mine head; his head had never been shaved since he was born; which was the order of the angel that foretold his birth, and it had been carefully observed to that time:

for I have been a Nazarite unto God from my mother's womb; one condition of which, or what was enjoined a Nazarite, was, that he should not be shaved, and which had been religiously observed in Samson; and whereas abstinence from wine and strong drink was another part of the law of Nazariteship, or what such persons were obliged unto, what Josephus says concerning Samson being drunk in the above cases could not be true; since his Nazariteship would have been made void by it, and so have affected his strength: but it must be owned that there were other things Nazarites were obliged to, which were dispensed with, as has been observed in the case of Samson, a perpetual Nazarite; and therefore it is probable, that the principal thing he was to regard, and upon which his strength was continued, was not shaving his head:

if I be shaven, then my strength will go from me, and I shall become weak, and be like any other man; in which he says more than he ever did before, namely, that his strength should go from him; for though that did not arise from his hair, yet the keeping on of that was the condition of his retaining it.

"And he showed her all his heart," i.e., he opened his mind thoroughly to her, and told her that no razor had come upon his head, because he was a Nazarite from his mother's womb (cf. Judges 13:5, Judges 13:7). "If I should be shave, my strength would depart from me, and I should be weak like all other men."

That he told her all his {i} heart, and said unto her, There hath not come a razor 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.

(i) Thus his immoderate affections toward a wicked woman caused him to lose God's excellent gifts, and become a slave to those whom he should have ruled.

16:17 If I be shaven - Not that his hair was in itself the cause of his strength, but because it was the chief condition of that covenant, whereby God was pleased to ingage himself to fit him for, and assist him in that great work to which he called him: but upon his violation of the condition, God justly withdraws his help. (EFN Isa 40:31 Psa 29:11)

17. if I be shaven, then my strength will go from me-His herculean powers did not arise from his hair, but from his peculiar relation to God as a Nazarite. His unshorn locks were a sign of his Nazaritism, and a pledge on the part of God that his supernatural strength would be continued.

16:4-17 Samson had been more than once brought into mischief and danger by the love of women, yet he would not take warning, but is again taken in the same snare, and this third time is fatal. Licentiousness is one of the things that take away the heart. This is a deep pit into which many have fallen; but from which few have escaped, and those by a miracle of mercy, with the loss of reputation and usefulness, of almost all, except their souls. The anguish of the suffering is ten thousand times greater than all the pleasures of the sin.
