Deuteronomy 29:18

Deuteronomy 29:18 In-Context

16 (for you know how we lived in the land of Mitzrayim, and how we came through the midst of the nations through which you passed;
17 and you have seen their abominations, and their idols, wood and stone, silver and gold, which were among them);
18 lest there should be among you man, or woman, or family, or tribe, whose heart turns away this day from the LORD our God, to go to serve the gods of those nations; lest there should be among you a root that bears gall and wormwood;
19 and it happen, when he hears the words of this curse, that he bless himself in his heart, saying, I shall have shalom, 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 anger of the LORD and his jealousy will smoke against that man, and all the curse that is written in this book shall lie on him, and the LORD will blot out his name from under the sky.
