Genesis 29:23-26

23And it came to pass in the evening, that he took Leah his daughter, and brought her to him; and he went in unto her.

24And Laban gave Zilpah his handmaid unto his daughter Leah for an handmaid.

25And it came to pass in the morning that, behold, it was Leah: and he said to Laban, What is this thou hast done unto me? did not I serve with thee for Rachel? wherefore then hast thou beguiled me?

26And Laban said, It is not so done in our place, to give the younger before the firstborn.
