Genesis 29:26

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

²⁵  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?

²⁶  And Laban said, It must not be so done in our country, to give the younger before the firstborn.

²⁷  Fulfil her week, and we will give thee this also for the service which thou shalt serve with me yet seven other years.

²⁸  And Jacob did so, and fulfilled her week: and he gave him Rachel his daughter to wife also.
