How does Dalila tempt Samson & why?
During the action of this poem (or play), Samson is in prison. While he is there, various people come to visit him. One of these is Dalila. When she comes to visit him, she tempts him by offerring him help and her love.
She tells Samson that she wants to help him in any way she can because she knows she deserves his anger and she has felt terrible about what she did to him.
Dalila is presumably motivated by guilt over her role in Samson's downfall. Her role in the work, though, is to allow Samson to show how much he has grown spiritually since he allowed her to tempt him before.
