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 to her. 24And Laban gave to his daughter Leah Zilpah his maid for an handmaid. 25And it came to pass, that in the morning, behold, it was Leah: and he said to Laban, What is this thou hast done to me? did I not serve with thee for Rachel? why then hast thou deceived me? 26And Laban said, It must not be so done in our country, to give the younger before the firstborn.1
