The Kotzker said as follows: Eliezer comes to the well. What does he see? What’s the first thing Eliezer sees? He sees Rivka go to the well, and miraculously, the water of the well rises so she can draw from it. Here’s the Kotzker: game over. You see a tzaddik (righteous person) who has miracles happening; that’s the one. Now, he still carries through his OG plan: “I’m going to go, I’m going to say this: if she says, ‘I’m going to give to you and to the camels,’ then that’s the one.” Why does he need the whole game and charade if he already saw that this woman is a tzaddik and she had the miracle? That’s it, she’s the one. The Kotzker answers: just because someone’s a tzaddik doesn’t mean that they’re perfect and that they’re right for you. That’s it. That’s it. A lot of times, people decide to get married because the guy—wow, you don’t know what a tzaddik this guy is. He’s, wow, unbelievable middot (character traits). He’s a tzaddik. Does that mean he’s your tzaddik? No. Sometimes we give up on things that we know we need because we’re dazzled and impressed by something else that is undoubtedly beautiful, and I’m sure that would also enhance your marriage, but that’s not what you need.
Now, this concept—the first lesson that we’re learning from Yitzchak and Rivka’s interaction—is that he brings her into the tent of Sarah imo (Sarah his mother), and as Rashi says, Veharei hi Sarah imo, she is what Sarah was, Vaye'ehaveha, and he loves her. Yitzchak waited to love her—not after a miracle, not after she’s a tzaddik, not after she covers herself and shows that she’s modest. He’s got all the signs. He’s got all the signs of an amazing girl, but does that mean that she’s my amazing girl? He’s got all the signs of an amazing girl, but does that mean that she’s my amazing girl?
