parsha bit: Toldot

[cellio]

The torah tells us that Yitzchak grew blind "from seeing". What does this mean? Rabbi Elazar ben Azariah said that his eyes grew faint from seeing the evil deeds of his son Eisav. According to him, God said to himself "should Yitzchak go out into the market and hear others speak of Eisav's evil deeds too?" So God dimmed his eyes so that he would stay home and be spared the embarrassment. (Genesis Rabbah 65:10)
