Genesis 29:27

Fulfil her week The seven days usually devoted to the feast and solemnity of marriage, Judges 14:12; for it does not appear that it relates to the seven years Jacob afterward served. This Laban seems to have desired, that by a week's cohabitation with Leah, his affections might be knit to her, and the marriage with her confirmed. We will give thee this also Hereby he drew Jacob into the sin, and snare, and disquiet of multiplying wives. Jacob did not design it, but to have kept as true to Rachel as his father had done to Rebekah; he that had lived without a wife to the eighty-fourth year of his age, could then have been very well content with one: but Laban, to dispose of his two daughters without portions, and to get seven years' service more out of Jacob, thus imposeth upon him, and draws him into such a strait, that he had some colourable reason for marrying them both.
