Or HaChaim on Genesis 24:29/אור החיים על בראשית כ״ד:כ״ט

1 ולרבקה אח ושמו לבן, Rebeccah had a brother called Laban. Our sages observe that whenever the Bible mentions righteous people, their name precedes them, whereas the reverse is the case when the Bible mentions wicked people (Esther Rabbah 6,3). Examples are Ruth 2,1; 1,2. Samuel I 25,3. It is puzzling then that Laban is introduced here in the manner of the righteous. In order to understand this we must pay attention to the verse describing Laban as running. Our sages in Yalkut Shimoni 109 state that as soon as Laban saw the nose-ring on Rebeccah he became greedy for money. This does not throw any light on our problem. The Torah should have written: "As soon as he saw the nose-ring, etc., Laban ran," instead of mentioning the fact that Laban saw the nose-ring after he had already commenced to run towards Eliezer. Besides, why did the Torah repeat the words: "to the man outside at the well" in verse 29 and then again in verse 30?

2The fact is that Laban was sincerely concerned about his sister's innocence, suspecting that the gifts to her of the jewelry by a total stranger could have been the beginning of an immoral relationship between them. The Torah here describes Laban as if he were a righteous person because it acknowledges his concern for his sister's chastity.

3When the Torah states: "it was when he saw," this shows that Laban reacted first to what he saw and subsequently to what he heard. As long as he had not yet heard what transpired between the two he put an ugly intepretation on the manner in which he thought his sister had obtained the jewelry, suspecting Eliezer of seducing Rebeccah. Laban nevertheless continued on his way to meet Eliezer and to offer him hospitality.
