Deuteronomy 29:19 in the King James Version
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:
Context
18 lest there should be among you man, woman, family, or tribe whose heart turns away today from the LORD our God, to go to serve the gods of those nations; lest there should be among you a root that produces bitter poison;
19 and it happen, when he hears 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.
20 The LORD will not pardon him, but then the LORD’s anger and his jealousy will smoke against that man, and all the curse that is written in this book will fall on him, and the LORD will blot out his name from under the sky.
