Why did David ask Jonathan about his guilt before Jonathan's father which caused him to seek David's life?
David did not know why Saul was upset with him. He did not know what he had done to cause Saul’s anger. It all seemed very irrational to him. As a result, he wanted to discover the reason for Saul’s hostility and he hoped that Jonathan could help him do so.1 Previously Jonathan was a means of reconciliation with Saul; he could possibly do the same again.2
1 David s'enfuit de Najoth, près de Rama. Il alla trouver Jonathan, et dit: Qu'ai-je fait? quel est mon crime, quel est mon péché aux yeux de ton père, pour qu'il en veuille à ma vie?
