Covering Up

We learned that when רבקה was coming with the servant to marry יצחק, she didn't know who he was. We learned that she saw him, fell off her camel, asked the servant who he was, the servant told her, and then she covered up her face.

This brings up the question of why she covered her face at all. If she was doing it to be צנוע, then why didn't she cover her face as soon as she saw יצחק instead of after she was told who he was? And if it wasn't because she was trying to be צנוע, then why would she cover herself? We said in class that she might have been doing it because she saw יצחק meditating and being close to 'ה and she might have felt insignificant and unworthy of marrying such a spiritual person. Therefore, she might have covered her face out of shame and/or embarrassment.

That brings up another question though. How did רבקה know that יצחק was having a spiritual connection with 'ה? She just saw him from far away. How would she have known whether or not he was doing a spiritual action? Also, Why would seeing a man sitting in a field be startling enough that she would fall off of her horse in the first place? It's not like they were the only people in the world, and she had lived around other people her entire life. She hadn't spent a long time wandering around with only a few select people for company. It just doesn't make sense to me.
