Salmi 10:7

His mouth is full of cursing and deceit and fraud: under his tongue [is] mischief and vanity.

Ver. 7. His mouth is full of cursing and deceit] Such cursing men are cursed men; and for such slippery and deceitful persons the Lord is the avenger of all such, 1 Tessalonicesi 4:8 .

Under his tongue is mischief] That is, in his heart, which is by nature placed beneath the tongue, making its use of it for much mischief, Mat 12:34 Giacomo 3:8. The word Toch, here rendered fraud, signifieth, properly, the middle of anything, Quoniam fraus in medio cordis est, saith R. David, because fraud is in the middle of the heart, and therehence sent into the mouth.
