Parshas Chayei Sorah:
Lavan went to Eliezer and found him waiting at the well. The posuk says: V'hinei omed al hagemalim al ha'ayin. Rashi says: Al hagmalim, LeShomron. he was guarding his camels.
We can now read the possuk: Lavan was standing and guarding the camels, and also guarding his eyes!
He is standing at a well at the time that the Sho'eivos go out, the gemoroh says that if someone goes to the riverside where the women are washing, if there is another route, he is called a rasha, even if he closes his eyes! Eliezer didn't have another route, he had to be there, but he was guarding his eyes just as he was guarding the camels.
Hinei omed al hagmalim al ha'ayin. He was omed on this, he made a conscious effort and put his mind to it.
