The home life of Rivka and Yitzchak was complicated. This is not to say there was a lack of love, honor or respect; in fact, quite the opposite is the case. Theirs is the first relationship the Torah explicitly states was one of love. Indeed, we might even say that theirs was love at first sight, and, as far as we can tell, that love continues until death separates them. What complicated their relationship were their children. After years of infertility, years of prayer and tears, Rivka became pregnant, but it was an unusual, difficult pregnancy, and it is likely that she was unaware that she was carrying twins.
