Boyd’s Bible Dictionary:
(fearful). An overseer of Saul’s herds (1 Sam. 21:7; 22:9-22).
Concise Bible Dictionary:
Chief of Saul’s herdmen, an Edomite, who informed Saul of David’s being aided by Ahimelech, and who afterward slew the latter and his house—85 priests (1 Sam. 21:7; 1 Sam. 22:9-22; Psa. 52 Title). We have no information as to how such a man could have been “detained before the Lord.” He may have been a proselyte and had some vow upon him.
