שמות, פרק כ״ב, פסוק י״ט

Serving God requires absolute loyalty, and any deviation shatters the foundational covenant between Him and His people. While the general prohibition against idolatry was already established in the Ten Commandments, the practical judgment and severe consequences for this betrayal are detailed here for the first time [רמב״ן, רבנו בחיי]. Because the Israelites had already received this warning, some suggest this specific decree is directed at the resident alien, establishing the complete rejection of idolatry as an absolute condition for living in the Land of Israel [אבן עזרא, חזקוני]. Others note that this law is placed immediately after prohibitions against immorality and sorcery because such sins frequently serve as gateways to idol worship [רלב״ג, בכור שור, קאסוטו].

The act of offering a sacrifice serves as a primary example rather than an exclusive rule. Just as bringing an offering is considered an inner service normally performed within the Temple for God, any similar inner service—such as burning incense, pouring water or wine, or bowing down—carries the death penalty if directed toward an idol. This applies even if these actions are not the standard way that particular idol is worshipped. In contrast, outer services, such as sweeping, washing, embracing, or kissing an idol, only carry the death penalty if they are the specific, established method of worshipping that exact statue [רש״י, רמב״ן, מזרחי, תורה תמימה].

This warning points directly back to the specific foreign gods the people were already commanded to reject at Mount Sinai [רש״י, רשב״ם, ביאור יש״ר]. However, the ban is all-encompassing. It prohibits the worship of any power other than God, whether they are idols of wood and stone, demons, abstract forces, or even ministering angels [רמב״ן, אבן עזרא, העמק דבר, שטיינזלץ].

The consequence for this betrayal is total condemnation. The primary approach among commentators is that this signifies execution by a court. However, others emphasize that the punishment also includes financial devastation, requiring the destruction of all the sinner's property, similar to the judgment of a corrupted city [שד״ל, קצור בעל הטורים, נתינה לגר]. A combined perspective suggests that while an individual offender is executed alone, an entire community that sins is destroyed along with all its possessions [אבן עזרא הקצר]. Beyond the physical penalty, there is a profound principle of measure for measure at play. Because the individual offered a sacrifice to an abomination, the person themselves becomes condemned, and deriving any benefit from the sacrifice is strictly forbidden [רבנו בחיי, ספורנו, טור הארוך].

Finally, the demand that worship be directed to God alone is meant to uproot two common theological mistakes. First, it rejects the belief that one can offer sacrifices to angels, treating them as intermediaries to appease God; all worship must be direct [רמב״ן, ביאור יש״ר, טור הארוך]. Second, it strictly forbids syncretism—the practice of worshipping God alongside other deities, as the Cutheans practiced. God demands pure devotion directed exclusively to His essence, without any shared allegiance [ספורנו, חזקוני, בכור שור, תורה תמימה].
