The mitzvah of honest weights in this week’s parsha highlights how even the slightest dishonesty in business is not just unethical—it reflects a deeper denial of Hashem and the truth of Yetziat Mitzrayim. The Rebbe teaches that being “just a little off” is already the beginning of self-deception. The real lesson is to take honest inventory at home and within ourselves, making sure our perspectives, judgments, and interactions are not subtly biased—because small distortions are the starting point of much greater dishonesty.
