The possession of his extraordinary strength is ascribed (e. g. Judges 13:25) to the presence of the Spirit of the Lord. Now the Lord, or the Spirit of the Lord, had departed from him, and so his strength had gone too. The practical lesson against the presumption of self-dependence, and the all-importance of a hearty dependence upon God's Holy Spirit, must not be overlooked.

And she said, the Philistines be upon thee, Samson,.... In like manner as she had before, that she might have full proof that the case was really such, that his strength was gone from him:

and he awoke out of his sleep; upon the cry she made: and said; within himself, purposing and determining in his own mind:

I will go out as at other times before; as he had done at the three former times, and did not meet with any Philistines to fall upon him, and so concluded it would be the case now, and he, if he did, should be able to defend himself against them:

and shake myself; that he might be thoroughly awake, and be on his guard and defence:

and he wist not that the Lord was departed from him; might have forgot what he had told Delilah of, and knew not what had been done to him, that his hair was shaved off; or if he did, was not sensible that the Lord had removed from him; but might hope that he would renew his strength, when he should stand in need of it; but he soon found his mistake; he was quickly taken by the Philistines, and ill used, and in a little time lost his life. And from hence it is thought sprung the story of Nisus, king of the Megarenses, who is supposed to reign about this time; of whom it is reported (h), that the hair of his head was of a purple colour, and was told by the oracle, that so long as that was kept on he should be safe, but if it was shaved off he should die; and so it was, that when the Cretians besieged him, his daughter falling in love with Minos, the king of the Cretians cut off her father's hair, and so both he and his country were delivered into the hands of the enemy.

She then cried out, "Philistines upon thee, Samson!" And he awaked out of his sleep, and thought ("said," i.e., to himself), "I will go away as time upon time (this as at other times), and shake myself loose," sc., from the fetters or from the hands of the Philistines; "but he knew not that Jehovah had departed from him." These last words are very important to observe in order to form a correct idea of the affair. Samson had said to Delilah, "If my hair were cut off, my strength would depart from me" (Judges 16:17). The historian observes, on the other hand, that "Jehovah had departed from him." The superhuman strength of Samson did not reside in his hair as hair, but in the fact that Jehovah was with or near him. But Jehovah was with him so long as he maintained his condition as a Nazarite. As soon as he broke away from this by sacrificing the hair which he wore in honour of the Lord, Jehovah departed from him, and with Jehovah went his strength.

(Note: "Samson was strong because he was dedicated to God, as long as he preserved the signs of his dedication. But as soon as he lost those signs, he fell into the utmost weakness in consequence. The whole of Samson's misfortune came upon him, therefore, because he attributed to himself some portion of what God did through him. God permitted him to lose his strength, that he might learn by experience how utterly powerless he was without the help of God. We have no better teachers than our own infirmities."-Berleb. Bible.)

And she said, The Philistines be upon thee, Samson. And he awoke out of his sleep, and said, I will go out as at other times before, and shake myself. And he wist not that the LORD was departed from him.

16:20 Said - Within himself. Shake myself - That is, put forth my strength. Knew not - Not distinctly feeling the loss of his hair, or not considering what would follow. Many have lost the favourable presence of God, and are not aware of it. They have provoked God to withdraw from them; but are not sensible of their loss.

Margin wist not

Contra, Ex 34:29.

20. he wist not that the Lord was departed from him-What a humiliating and painful spectacle! Deprived of the divine influences, degraded in his character, and yet, through the infatuation of a guilty passion, scarcely awake to the wretchedness of his fallen condition!

16:18-21 See the fatal effects of false security. Satan ruins men by flattering them into a good opinion of their own safety, and so bringing them to mind nothing, and fear nothing; and then he robs them of their strength and honour, and leads them captive at his will. When we sleep our spiritual enemies do not. Samson's eyes were the inlets of his sin, (ver. 1,) and now his punishment began there. Now the Philistines blinded him, he had time to remember how his own lust had before blinded him. The best way to preserve the eyes, is, to turn them away from beholding vanity. Take warning by his fall, carefully to watch against all fleshly lusts; for all our glory is gone, and our defence departed from us, when our separation to God, as spiritual Nazarites, is profaned.
