C. F. Keil and Franz Delitzsch on Genesis 29:21-24

Gen 29:21-24

But when Jacob asked for his reward at the expiration of this period, and according to the usual custom a great marriage feast had been prepared, instead of Rachel, Laban took his elder daughter Leah into the bride-chamber, and Jacob went in unto her, without discovering in the dark the deception that had been practised. Thus the overreacher of Esau was overreached himself, and sin was punished by sin.
