Genesis 29:24-26

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

And it came to pass, that in the morning, 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?

And Laban said, It must not be so done in our country, to give the younger before the firstborn.
