After violating a direct command from God, the prophet from Judah completes his meal at the home of the older prophet. The divine message detailing his punishment arrives the exact moment he finishes eating and drinking [ביאור שטיינזלץ].
This sequence of events highlights a tragic spiritual decline, showing how one failure naturally leads to another. The prophet from Judah does not merely stumble by taking a single bite of food; he stays to consume the entire meal and then goes so far as to accept a gift. Simple logic should have guided him: if God strictly forbade him from eating in that place, He certainly forbade accepting property from its residents [מלבי״ם].
As the younger prophet prepares to leave, the older prophet—the very man who had convinced him to turn back—personally saddles a donkey for him. The primary approach among commentators is that the older prophet does this with his own hands to show honor to his guest [אברבנאל] and to offer a gesture of friendship [ביאור שטיינזלץ]. The animal being saddled belongs to the older prophet, as the prophet from Judah had originally traveled on foot and did not own a donkey of his own [מלבי״ם].
