A profound moment of national recommitment requires more than a broad promise; it demands addressing past mistakes directly. The people take a severe oath to observe the laws of the Torah, explicitly detailing specific areas that require special attention and strengthening. Their oath serves as a binding pledge that links their general acceptance of the law to a concrete list of commitments [מצודת דוד].
The decision to highlight particular Commandments is intentional. The people list the very areas where they had previously failed, most notably the strict prohibition against assimilation and intermarrying with foreign nations [רלב״ג]. Furthermore, this renewed commitment against intermarriage is entirely comprehensive. It applies to all the nations in their surrounding region, extending even to those groups that were not part of the original seven Canaanite nations explicitly forbidden in the Torah [מלבי״ם].
