שופטים, פרק י״ט, פסוק ז׳

As the man stands up with the intention to leave, his father-in-law steps in to stop him. The host applies heavy pressure, using strong persuasion and deep urging to keep his son-in-law from departing [מצודת ציון].

Faced with this intense insistence, the man gives in and changes his mind. He decides to stay where he is, spending an additional night at his father-in-law's house. This extra night marks the fourth day of his overall visit [ביאור שטיינזלץ].
