1 Samuel 20:8

⁶  If thy father at all miss me, then say, David earnestly asked leave of me that he might run to Bethlehem his city: for there is a yearly sacrifice there for all the family.

⁷  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.

⁸  Therefore thou shalt deal kindly with thy servant; for thou hast brought thy servant into a covenant of the LORD with thee: notwithstanding, if there be in me iniquity, slay me thyself; for why shouldest thou bring me to thy father?

⁹  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?

¹⁰  Then said David to Jonathan, Who shall tell me? or what if thy father answer thee roughly?
