1 Samuel 20:33 in the King James Version
And Saul cast a javelin at him to smite him: whereby Jonathan knew that it was determined of his father to slay David.
Context
32 Jonathan answered Saul his father, and said to him, “Why should he be put to death? What has he done?”
33 Saul cast his spear at him to strike him. By this Jonathan knew that his father was determined to put David to death.
34 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 treated him shamefully.
