Deuteronomy 8:18

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.

[8:18]  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.
