Why Rivkah was so struck seeing Yitzchak for the first time
When Rivka lifted her eyes and saw Yitzchak, she beheld him still standing in prayer, and at that moment he appeared like an angel of G-d, awesome in his bearing. The Netziv's point is that Yitzchak's greatness was revealed precisely through his posture of tefillah (prayer), which transformed his countenance into something exalted and otherworldly. It was this vision of holiness, rather than ordinary human appearance, that so struck Rivka upon first encountering her future husband.AI summary · anthropic/claude-sonnet-5
