20 Then she called, "Samson, the Philistines are upon you!" He awoke from his sleep and thought, "I'll go out as before and shake myself free." But he did not know that the Lord had left him.

Matthew Henry's Commentary on Judges 16:20

Commentary on Judges 16:18-21

(Read Judges 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, verse 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.
