Following the sin of the Golden Calf, God issues a severe warning demanding the total eradication of all idolatry, its symbols, and its accessories [ביאור שטיינזלץ]. This strict directive serves as a deterrent to prevent the Israelites from repeating such foolishness [בכור שור]. The instructions detail the exact measures to be taken against various cultic symbols, beginning with the complete smashing and destruction of idol altars [אבן עזרא, ביאור יש״ר, ביאור שטיינזלץ].
The command then targets the Asherah trees. The primary approach among commentators is that these were actual trees either worshipped directly or planted in honor of an idol [רש״י, אבן עזרא הקצר, ביאור יש״ר]. Alternatively, these were wooden cultic objects, such as tree trunks or pillars, positioned near altars to symbolize the Canaanite goddess Asherah and her fertility, rather than literal statues of the deity [קאסוטו]. The specific action required for these trees involves two distinct forms of destruction, depending on their origin. Trees planted specifically for worship must be entirely uprooted and ruined, while naturally growing trees that were only later used for idolatry simply need their newer, worshipped branches chopped off [הכתב והקבלה].
A striking difference exists between these instructions and the parallel directives given before the sin of the Golden Calf. Following their failure, the demands placed upon the Israelites became significantly stricter. They are now required to destroy idolatrous items immediately, even before they finish conquering the land [העמק דבר]. Furthermore, earlier commands only required the destruction of stone pillars erected for bowing, but now altars—which are essentially accessories to worship—are explicitly targeted [העמק דבר]. Another perspective suggests that the destruction of altars was always implied; since an altar requires much more effort to build than a simple stone pillar, the command to destroy the simpler pillars naturally included the more complex altars [פרדס יוסף].
The most significant new requirement is the destruction of the Asherah trees. Before the Golden Calf, the Israelites were untainted by idolatry, meaning the Canaanite trees were viewed simply as a harmless inheritance they could use and enjoy. However, once they worshipped the calf, they revealed a susceptibility to idol worship, rendering these trees strictly forbidden and marked for destruction [העמק דבר, הכתב והקבלה, מלבי״ם, פרדס יוסף]. Interestingly, while the altars and stone pillars are addressed as a plural group, the trees are mentioned in the singular. This shift may hint at the Israelites' own personal idolatrous trees resulting from their sin [העמק דבר]. Alternatively, while all altars and pillars were universally banned, only a very small fraction of trees were actually worshipped during the brief period between the sin of the Golden Calf and the people's repentance, accounting for the singular form [פרדס יוסף]. On a conceptual level, the specific term used for the trees shares a root with the word for happiness, suggesting that fortunate and happy is the person who actively roots out and destroys idolatry [שפתי כהן].
