Targum zu Bereschit 29:22

And Laban gathered all the men of the place, and made them a feast. Answering he said to them, Behold, seven years since Jakob came to us the wells have not failed and the watered places are multiplied: and now come, let us counsel against him cunning counsel, that he may remain with us. And they gave him cunning counsel that he should take Leah to him instead of Rahel.

And Laban gathered all the people of the place, and made a feast. And Laban answered and said to them, Behold seven years are from the coming of this just man to us; our waterings have not failed, and our springs are many: and now come, give me counsel how we may settle (or subject) him among us yet seven years. And they gave him cunning counsel to take Leah to him instead of Rahel.
