Matthew Poole and continuators on Psalms 52:2

2. Thy tongue deviseth mischiefs like a sharp rasor, working deceitfully .

(i. e.) Expresseth what thy wicked Mind had devised. Thus Skilfulness is ascribed to those [illegible: 1 word], which are governed by a skilful or prudent Man, Psal. 78. last. This Word implies that Doeg's Words were not uttered rashly and unadvisedly, but with Premeditated malice, and a mischievous Design, which he waited for an Opportunity to Execute; and therefore he readily took the first occasion which offered it self.

Wherewith a man pretending onely to shave off the Hair, doth suddenly a[illegible: 1+ letters]d unexpectedly cut the Throat. So Doeg pretended onely to Vindicate himself from the Imputation of Disloyalty, 1 Sam. 22. 8. but really intended to expose the Priests, who were Friends to David, to the Kings fury and Cruelty.
