The proper name of the woman from the Valley of Sorek who became Samson's lover and ultimately betrayed him to the Philistine lords. Her name may be related to the Hebrew root דלל meaning 'to hang down' or 'to be weak,' or to the Arabic word for 'coquette,' though the etymology remains debated. All six occurrences appear within a single narrative unit in Judges 16:4-18, where Delilah persistently presses Samson to reveal the secret of his strength, eventually succeeding and delivering him to his enemies.
