Then Saul's anger was kindled against Jonathan, and he said to him, You son of a perverse rebellious woman, don't I know that you have chosen the son of Jesse to your own shame, and to the shame of your mother's nakedness?
"Neither you nor your kingdom shall be established"  (1 Samuel 20:31). From this it is clear that Saul did not believe the word of the prophet Samuel who had told him long previously that his kingdom would not continue.  In this unbelief of God's prophet, the sin of Saul was approaching its climax.  He was in this purpose the avowed enemy, not only of David, but of God Himself.  He would continue to be king, so he thought, in spite of the will of God; and here it appears that he expected Jonathan to succeed him and continue his dynasty.
