whose mouth is full of cursing and bitterness;"
His mouth is full of cursing and deceit and fraud; under his tongue are mischief and vanity.
For the sin of their mouth is the word of their lips, even let them be taken in their pride; and for cursing and the lying which they speak.
Let all bitterness and wrath and anger and tumult and evil speaking be put away from you, with all malice.
Out of the same mouth proceeds blessing and cursing. My brothers, these things ought not to be so.
