1 Samuel 20:2-6

And he said unto him, God forbid; thou shalt not die: behold, my father will do nothing either great or small, but that he will shew it me: and why should my father hide this thing from me? it is not so.

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.
