1 Samuel 20
30 Ref 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?
31 Ref For as long as the son of Jesse lives on the earth, you shall not be established, nor your kingdom. Therefore now send and bring him to me, for he shall surely die.
32 Ref Jonathan answered Saul his father, and said to him, "Why should he be put to death? What has he done?"
33 Ref Saul cast his spear at him to strike him. By this Jonathan knew that his father was determined to put David to death.
34 Ref So Jonathan arose from the table in fierce anger, and ate no food the second day of the month; for he was grieved for David, because his father had done him shame.
