Jamieson, Fausset and Brown on 1 Samuel 6:2-3

2-3. the Philistines called for the priests and the diviners--The designed restoration of the ark was not, it seems, universally approved of, and many doubts were expressed whether the prevailing pestilence was really a judgment of Heaven. The priests and diviners united all parties by recommending a course which would enable them easily to discriminate the true character of the calamities, and at the same time to propitiate the incensed Deity for any acts of disrespect which might have been shown to His ark.
