Matthew Henry on 1 Samuel 20:35–end
Here is, 1. Jonathan's faithful performance of his promise to give David notice of the success of his dangerous experiment. He went at the time and to the place appointed (Sa1 20:35), within sight of which he knew David lay hid, sent his footboy to fetch his arrows, which he would shoot at random (Sa1 20:36), and gave David the fatal signal by shooting an arrow beyond the lad (Sa1 20:37): Is not the arrow beyond thee?
