1 Samuel 20:5 (KJV)

And David sware moreover, and said, Thy father certainly knoweth that I have found grace in thine eyes; and he saith, Let not Jonathan know this, lest he be grieved: but truly as the Lord liveth, and as thy soul liveth, there is but a step between me and death.

Then said Jonathan unto David, Whatsoever thy soul desireth, I will even do it for thee.

And David said unto Jonathan, Behold, to morrow is the new moon, and I should not fail to sit with the king at meat: but let me go, that I may hide myself in the field unto the third day at even.

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

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.
