And she said unto him, How canst thou say, I love thee, when thine heart is not with me? thou hast mocked me these three times, and hast not told me wherein thy great strength lieth.

And Dalila said to him: How dost thou say thou lovest me, when thy mind is not with me? Thou hast told me lies these three times, and wouldst not tell me wherein thy great strength lieth.

And she saith unto him, 'How dost thou say, I have loved thee, and thy heart is not with me? these three times thou hast played upon me, and hast not declared to me wherein thy great power is.'

And she said to him, Why do you say you are my lover when your heart is not mine? Three times you have made sport of me, and have not made clear to me the secret of your great strength.

And Delilah said to him: "How can you say that you love me, when your soul is not with me? You have lied to me on three occasions, and you are not willing to reveal wherein lies your very great strength."

And she said unto him, How canst thou say, (h) I love thee, when thine heart [is] not with me? thou hast mocked me these three times, and hast not told me wherein thy great strength [lieth].
(h) For Samson used to say "I love you".

And she said unto him, how canst thou say, I love thee, when thine heart is not with me?.... She took an opportunity, when he was caressing her, to upbraid him with dissembled love, and a false heart: thou hast mocked me these three times; she had urged him to tell her where his strength lay, and by what it might be weakened, first pretending it might be done by binding him with green withs, and then with new ropes, and a third time by weaving his locks into the web:
and hast not told me wherein thy great strength lieth; the thing so frequently and so importunately requested.

This last step was very speedily to follow - Judges 16:15 After this triple deception, Delilah said to him, "How canst thou say, I love thee, as thine heart is not with me" (ie, not devoted to me)?

Not with me - Not open to me.
