Saul would miss David at his feast not only because his seat would be vacant but because warriors normally expressed their support for their king by eating with him at important meals (v. 18). David's absence would have raised a question in Saul's mind about David's commitment to him. The writer did not identify the exact place where David had previously hidden himself on some eventful day (v. 19). Evidently it was near the stone Ezel, a site unknown today but well-known then. Probably Jonathan chose this place to communicate with David because it was convenient and secure, evidently near Gibeah.
The shooting of arrows was probably just a practical way to signal David. Jonathan reminded David of their agreement as they parted (v. 23; cf. Gen. 31:48-53).223
"Friendships are one of the most enriching of life's experiences: how poor is the man or woman who is friendless! Friends enrich life because they give, without counting the cost. Jonathan was a man who gave to David more than he received; and in doing so he showed how different he was from the typical king described in 8:11-17, whose sole function was to take. Life has its givers and its takers; Jonathan was supremely a giver--and David, though destined to become a king, persistently declined to take anything away from Saul. He patiently waited for God to give him the crown of Israel."224
