Genesis 29:21-28 Holman Christian Standard Bible (HCSB)
21 Then Jacob said to Laban, “Give me my wife, for my time is completed. I want to sleep with[a] her.” 22 So Laban invited all the men of the place to a feast. 23 That evening, Laban took his daughter Leah and gave her to Jacob, and he slept with her. 24 And Laban gave his slave Zilpah to his daughter Leah as her slave.
25 When morning came, there was Leah! So he said to Laban, “What is this you have done to me? Wasn’t it for Rachel that I worked for you? Why have you deceived me?”
26 Laban answered, “It is not the custom in this place to give the younger daughter in marriage before the firstborn. 27 Complete this week of wedding celebration, and we will also give you this younger one in return for working yet another seven years for me.”
28 And Jacob did just that. He finished the week of celebration, and Laban gave him his daughter Rachel as his wife.
