Doeg
The name Doeg means “careful, who acts with uneasiness”.
Easton's Bible Dictionary 1897
Fearful, an Edomite, the chief overseer of Saul’s flocks (1 Sam. 21:7). At the command of Saul he slew the high priest Ahimelech (q.v.) at Nob, together with all the priests to the number of eighty-five persons. (Comp. Ps. 52, title.)
Smith's Bible Dictionary 1863
International Standard Bible Encyclopedia 1915
do'-eg (do'-egh "anxious," "cared for"): "The Edomite," a servant of Saul, who watched David's intercourse with the priest Ahimelech, then denounced the priest to the king, and later executed his command to slay the priests at Nob. The position he held is described as that of "the mightiest" of Samuel's herdsmen (1Sa 21:7 margin). Septuagint reads: "tending the mules." Rabbinical legends speak of him as the greatest scholar of his time. The traditional title of Ps 52 associates the composition of that Psalms with the events that led to the slaying of the priests (1Sa 21:7; 22:9,18,22).
