He sent messengers to Abimelech in secret and told him, "Look out! Ebed's son Gaal and his family have arrived here in Shechem. Watch out! They're stirring up the city against you.

So Delilah asked Samson, "Please tell me the secret to your great strength and how you may be tied up and tortured."

Meanwhile, some kidnappers were hiding inside an inner room, waiting for her signal. So she told him, "The Philistines are attacking you!" But he snapped the cords as one might break a burned candle wick. So his secret remained undiscovered.
