A king's deepest anguish does not always come from foreign armies, but from the sudden, shocking betrayal of those he trusts most. David's cry stems from a profound pain over a rebellion that is entirely internal, erupting from within his own home and his own nation [ביאור שטיינזלץ]. The sheer scale of this treason leaves him in a state of immense astonishment and disbelief at the severe reality unfolding around him [אבן עזרא].
The threat he faces is twofold. On one side are his clear, established adversaries, such as hostile members of the tribe of Benjamin. Far more devastating, however, are the individuals closest to him who have suddenly risen up in revolt. This inner circle of betrayal is led by his own son Absalom and his nephew Amasa, drawing away a massive following from the Israelites [אבן עזרא, רד״ק, מצודת דוד, מאירי]. The coordinated effort between these different factions highlights a deeply organized, unified plot specifically designed to bring him down [רד״ק].
The sheer number of rebels is overwhelming, but the primary approach among commentators is that the danger lies equally in their quality, status, and power. These are not common soldiers; they are highly important and respected leaders [מאירי]. They are individuals of exceptional stature, possessing greatness in Torah study, profound wisdom, vast wealth, or even intimidating physical size [רש״י]. Throughout his life, David faced enemies of immense power, from King Saul and terrifying giants to cunning figures like Doeg the Edomite, Ahithophel, and Shimei son of Gera, who dared to publicly throw stones at him [רש״י, רד״ק, מצודת דוד].
By emphasizing the elite status and overwhelming strength of his attackers, David acknowledges his complete vulnerability. He recognizes that if God does not intervene to save him, he has absolutely no chance of survival and will inevitably fall into their hands [מאירי]. Furthermore, this coordinated assault is not merely a physical threat to his life and kingship; it is a direct attack aimed at breaking his spiritual soul [מלבי״ם].
