שמואל א, פרק י״ז, פסוק כ״ח

A young man's sudden arrival at the battlefront and his bold conversations with the soldiers spark a harsh confrontation with his older brother. Eliab's severe reaction to David's presence stems from a complex mix of misunderstanding and genuine worry. Upon realizing that David actually intends to fight the Philistine, Eliab becomes deeply angry, viewing the situation as a deadly danger from which his younger brother cannot possibly survive [רד״ק].

Fueled by this anger, Eliab hurls two main accusations at David [מלבי״ם]. First, he questions David's motives for being at the camp. Unaware that their father specifically sent David on an errand [מצודת דוד], Eliab assumes his brother arrived entirely on his own initiative [מלבי״ם]. He accuses David of coming simply to enjoy the spectacle of the battle [מצודת דוד], driven by childish curiosity and a lack of responsibility [ביאור שטיינזלץ].

The second accusation strikes at David's daily duties. Eliab fiercely scolds him for abandoning his flock of sheep [מצודת ציון, ביאור שטיינזלץ]. The gravity of this neglect is magnified because the animals were left in a remote pasture near the desert [מצודת ציון], an area highly vulnerable to predators and wandering robbers [מצודת דוד].

Eliab explicitly connects these two actions to deep character flaws [מלבי״ם]. He accuses David of pure recklessness, a carelessness that is evident both in his willingness to risk his own life and in his decision to leave the sheep unattended [רד״ק, ביאור שטיינזלץ]. Ultimately, Eliab attributes David's independent arrival at the war camp to this reckless attitude, while blaming the abandonment of the defenseless flock on a fundamental badness of heart [מלבי״ם].
