Delilah asks this question to say that if Samson really loved her he would tell her his secrets. This question can be written as a statement. AT: "When you say 'I love you,' you are lying because you do not share your secrets with me." (See: [[rc://en/ta/man/translate/figs-rquestion]])
Here the author speaks of how Delilah tries to persuade Samson as if she were putting pressure on him to convince him to tell her what she wants to know. AT: "tried hard to persuade him ... kept trying to persuade him" (See: [[rc://en/ta/man/translate/figs-idiom]])
The author used a hyperbole, an exaggeration, to emphasize how miserable Sampson felt. AT: "that he was completely miserable" or "that he was very unhappy" (See: [[rc://en/ta/man/translate/figs-hyperbole]])
