Looking back across the long chain of generations brings a deep, overwhelming sense of regret. A profound realization of prolonged failures against God causes the people to feel entirely surrounded by their own guilt [ביאור שטיינזלץ]. The experience of this guilt is vividly compared to a physical state of resting on a bed of shame and being wrapped from above in a blanket of disgrace [מצודת דוד]. This act of lying down represents a state of utter helplessness. Just as a person overwhelmed by deep trouble might throw themselves down to sleep out of sheer despair, the nation sinks heavily into its own sadness and inaction [רד״ק].
There is a careful distinction in this imagery between the different layers of humiliation. Shame is an internal feeling that grows from within a person, which is why it is compared to the close, physical act of lying down. Disgrace, on the other hand, is the humiliation that comes from the outside world, perfectly captured by the image of a heavy covering placed over the body from above [מלבי״ם].
The crushing weight of these feelings comes from the sudden, sharp awareness of having failed God, as there is simply no shame greater than sinning against Him [מצודת דוד]. These failures are not new; they have trailed the people from their very youth, tracing back to the earliest days when God first chose them to be His nation [מצודת דוד]. This reflects a tragic historical cycle where children stubbornly held onto the destructive habits of their fathers, repeating the exact same wrongs they witnessed in the generations before them [רד״ק]. Ultimately, the repeated acknowledgment of ignoring God's voice serves to heavily emphasize the sheer severity of their actions and their long history of turning away from His word [מצודת דוד].
