‘ And when Delilah saw that he had told her all his heart, she sent and called for the lords of the Philistines, saying, “Come up this once, for he has told me all his heart.” Then the lords of the Philistines came up to her, and brought money in their hand.'
This time Delilah realised that he had really bared his heart, and she felt justified in again calling the Philistine Tyrants for one last attempt. And she convinced them too, for they came bringing the promised reward with them.
For ‘he has told me all his heart' there is an alternative reading ‘he has told her all his heart'. If this be read then it signifies the words of the messengers whom she sent.
