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, even as he has to this day.

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.
