True faith demands absolute loyalty. It is not enough to simply avoid doing wrong or worshipping false gods; one must completely disconnect from their symbols, their ways, and even their memory. The path of those who abandon God is filled with multiplying pains and troubles. The primary approach among commentators is that these hardships increase because the wicked rush toward foreign gods and destructive paths [רש״י, רד״ק, מאירי]. Some add that the righteous will actively pursue these individuals, bringing further sadness to their hearts [מצודת דוד]. Alternatively, this pursuit of false gods can be understood as a kind of transaction. In this view, the transgressors are essentially paying a dowry, purchasing new deities and binding themselves to foreign nations as if becoming betrothed to idolatry [רש״י, אבן עזרא, מאירי, מצודת דוד, מלבי״ם]. Another perspective simply views this as the act of exchanging or swapping one's true faith for a false one [ביאור שטיינזלץ].
This commitment to God involves a firm rejection of corrupt practices. On a ritual level, this means a total refusal to participate in pagan ceremonies, specifically the pouring or throwing of blood for idols [רש״י, מצודת דוד, אבן עזרא, ביאור שטיינזלץ, מלבי״ם]. In Jewish law, the act of throwing blood in the context of idol worship is treated with the exact same severity as pouring a formal libation [תורה תמימה]. Beyond the ritual, there is a profound moral interpretation. Blood can symbolize violence and robbery. The offerings of the wicked are tainted with the blood of those they have exploited, demonstrating that sacrifices accompanied by evil deeds offer no spiritual benefit and only cause harm [רד״ק, מאירי]. On a more personal level, this can be seen as King David speaking directly about his enemies who sought his ruin. In a display of profound restraint, David declares that he will not shed their blood in revenge, even though they publicly shamed him and sought his life [אלשיך].
The ultimate expression of this separation is a vow of silence regarding the corrupt. The primary approach among commentators is that this is a strict commitment never to utter the names of idols or superstitions, ensuring they are completely forgotten and erased from memory. Others suggest that the refusal to speak these names applies to the wicked people themselves [רד״ק]. Finally, reflecting a deeply noble character, this silence is seen as David's personal promise not to speak poorly of his enemies or mention their names in disgrace [אלשיך].
