There are multiple origins and translations for the name Delilah:
1. Hebrew (דלילה) means - "one who weakened or uprooted; weak or poor" appears only in the Hebrew bible Book of Judges 16, where she is the "woman in the valley of Sorek" whom Samson loved, and who was his downfall. Her figure, one of several dangerous temptresses in the Hebrew bible, has become emblematic: "Samson loved Delilah, she betrayed him, and, what is worse, she did it for money".
2. Arabic name (دليلة) semantics - "showing the way", see the name Dalila.
