The tongue deviseth mischiefs; like a sharp razor, working deceitfully.

What shall be given unto thee? or what shall be done unto thee, thou false tongue? / Sharp arrows of the mighty, with coals of juniper.

My brethren have dealt deceitfully as a brook, and as the stream of brooks they pass away; / Which are blackish by reason of the ice, and wherein the snow is hid: / What time they wax warm, they vanish: when it is hot, they are consumed out of their place.

Keep thy tongue from evil, and thy lips from speaking guile.

Though wickedness be sweet in his mouth, though he hide it under his tongue; Though he spare it, and forsake it not; but keep it still within his mouth: Yet his meat in his bowels is turned, it is the gall of asps within him.

She openeth her mouth with wisdom; and in her tongue is the law of kindness.
