because when such a person hears the words of this oath, he invokes a blessing on himself, saying, ‘I will have peace, even though I walk in the stubbornness of my own heart.’ This will bring disaster on the watered land as well as the dry.
KJV
And it come to pass, when he heareth the words of this curse, that he bless himself in his heart, saying, I shall have peace, though I walk in the imagination of mine heart, to add drunkenness to thirst:
ASV
and it come to pass, when he heareth the words of this curse, that he bless himself in his heart, saying, I shall have peace, though I walk in the stubbornness of my heart, to destroy the moist with the dry.
