1 Samuel 20:7, 9, 33

If he say thus, It is well; thy servant shall have peace: but if he be very wroth, then be sure that evil is determined by him.

And Jonathan said, Far be it from thee: for if I knew certainly that evil were determined by my father to come upon thee, then would not I tell it thee?

And Saul cast a javelin at him to smite him: whereby Jonathan knew that it was determined of his father to slay David.
