Deuteronomy 8:18-20

8:18 You must remember the Lord your God, for he is the one who gives ability to get wealth; if you do this he will confirm his covenant that he made by oath to your ancestors, ¹  even as he has to this day. 8:19 Now if you forget the Lord your God at all ²  and follow other gods, worshiping and prostrating yourselves before them, I testify to you today that you will surely be annihilated. 8:20 Just like the nations the Lord is about to destroy from your sight, so he will do to you ³  because you would not obey him. ⁴ 

[8:18]  ¹ tc Smr and Lucian add “Abraham, Isaac, and Jacob,” the standard way of rendering this almost stereotypical formula (cf. Deut 1:8; 6:10; 9:5, 27; 29:13; 30:20; 34:4). The MT’s harder reading presumptively argues for its originality, however.

[8:19]  ² tn Heb “if forgetting, you forget.” The infinitive absolute is used for emphasis; the translation indicates this with the words “at all” (cf. KJV).

[8:20]  ³ tn Heb “so you will perish.”

[8:20]  ⁴ tn Heb “listen to the voice of the Lord your God.” The pronoun has been used in the translation for stylistic reasons to avoid redundancy.
