1 Samuel 20:24-26

David hid himself in the field Namely, at the time appointed: for it seems probable that he went first to Beth-lehem, and thence returned to the field, when the occasion required. Jonathan arose He rose from his seat where he had sat next the king, and stood up at Abner's coming, to do honour to him, who was his father's cousin, and the general of the army. Something hath befallen him Some accident, which has rendered him unclean, and so unfit to partake of this feast, which consisted in part of the remainders of the peace-offerings, according to the law; (Leviticus 7:20;) unfit also to come into any company, much more, into the king's company, lest he should pollute them also.
