A severe curse is directed at the wicked, asking that past wrongdoings never fade from memory. Instead, these sins should remain constantly visible before God, ultimately leading to total destruction. Commentators generally agree that this targets the sins of the wicked person's parents, which were mentioned previously. Repeating the mention of these sins serves to emphasize the sheer severity of their actions [רד״ק].
These sins do not just sit passively in the past. Their constant presence before God acts as an ongoing accusation against the sinner [אלשיך, מצודת דוד]. The ultimate goal of this relentless prosecution is a harsh final outcome: the complete erasure of the sinners' memory from the world.
Regarding the identity of the sinners facing such total erasure, different perspectives exist. One approach suggests that this curse is aimed directly at Esau and his leaders [רש״י]. Conversely, another view understands these words as a direct quote of the enemies cursing David. In this light, it is the enemies who are demanding the complete removal of any memory of David and his parents from the earth [ביאור שטיינזלץ].
