Rashi on Deuteronomy 25:17/רש"י על דברים כ״ה:י״ז

1זכור את אשר עשה לך REMEMBER WHAT [AMALEK] DID UNTO THEE — If you use false weights and measures then you must apprehend the provocation of the enemy, as it states (Proverbs 11:1): “A false balance is an abomination to the Lord, etc.”, and there is written immediately after this (v. 2): “If intentional sin comes, shame comes”(Midrash Tanchuma, Ki Teitzei 8).
