1 Samuel 22:18 - Joseph Benson’s Commentary on the Old and New Testaments

Doeg the Edomite turned and fell upon the priests The country of Doeg is very properly here mentioned, and again repeated, to wipe off the stain of this butchery from the Israelitish nation, and to show why he was so ready to do it; because he was one of that nation which had an implacable hatred against all Israelites, and against the priests of the Lord. And slew on that day fourscore and five persons “The massacre of these innocent men was so outrageous, so bloody, and so horrible, that it paints the character of Saul in the blackest colours, and exposes him as a warning, not only to tyrannical monarchs, but likewise to private persons, who give a loose to the instigations of jealous suspicions and intemperate wrath.” Chandler. That did wear a linen ephod That is, ministered unto the Lord; but we are not to understand by the ephod such a garment as the high-priest wore, for this is distinguished from the high-priest's ephod by the matter of it, which was merely linen. The priests had probably all put on this habit, on account of appearing before the king.
