Devarim 29:18-20

Orthodox Jewish Bible

^18 (17) Lest there should be among you ish, or isha, or mishpochah, or shevet, whose lev turneth away today from Hashem Eloheinu to go and serve the elohei hagoyim hahem (the g-ds of these Goyim); lest there should be among you a shoresh that beareth bitter poison and wormwood [MJ 12:15];

^19 (18) And it come to pass, when he heareth the divrei haalah (words of this oath, imprecation) that he bless himself in his lev, saying, Shalom be with me, though I walk in the stubbornness of mine lev—thus bringing disaster on both the watered and the thirsty.

^20 (19) Hashem will not spare him, but then the wrath of Hashem and His kina (jealousy) shall burn against that ish, and kol haalah (all the curses) that are written in this sefer shall fall upon him, and Hashem shall blot out shmo from under Shomayim.
