I will shoot three arrows. — The two friends agree on a sign. It was a very simple one, and seems to speak of very early primitive times. Jonathan slightly varies from his original purpose. In 1 Samuel 20:12 it seems as though he meant to have sent a special messenger had the news been good, but now the arrangement is that in either event he should come himself out from the city into the solitary valley where it was agreed David should remain in hiding by the stone “Ezel.” Dean Payne Smith rather strangely conceives that the arrows of the “sign” were to be aimed at the stone Ezel, but the description points to the “mark” as situated on the side of “Ezel,” in or behind which David was to be concealed.
The prince agreed that after the feast he would leave the city, as though about to practise shooting at a mark, and that he would bring with him a servant — probably-one of his young armour-bearers — when, at the spot agreed upon in the neighbourhood of David’s place of concealment near Ezel, he would post his servant in his place as marker, and then would shoot. After shooting, he would call out to his attendant, “the arrows are on this side of thee” (that is, between the mark and Jonathan himself), then David would know all was well; but if he cried “the arrows are beyond thee,” that is, on the further side of the mark, David would understand that all was over, and that he must fly. Jonathan evidently took these precautions not knowing whether or no he would be accompanied by friends of his father from the city, in which case the “sign” agreed upon would be sufficient to tell David what had happened at the feast. As it turned out, Jonathan was able to escape observation, and to go alone with his servant to the place of meeting. He used the sign to attract his friend’s attention, and then followed the last sorrowful parting, told in 1 Samuel 20:41-42.
