The success of Laban’s deceitful substitution of Leah for Rachel may be mysterious to us. How could Jacob not detect this ploy? The answer is that the two sisters may have been quite similar.
We will meet with deceivers in our path through life. How do we cope with them? One answer is always that we pray to the Lord about all major decisions and milestones in life. It was by failing to consult the Lord that Israel was led to make an alliance with the deceitful Gibeonites and were taken in by their lie (Joshua 9:14).
What should Jacob have done? It is not necessary to always know what someone should have done; it is enough to know what he should not have done, and Jacob should not have had two wives, nor should he have involved the maids later. Perhaps we could say that he should either have made up his mind that although it would be very hurtful to Leah, and it would have shamed her, he should have divorced Leah, if he was so very set on Rachel, or he should have stayed with Leah: one or the other, and he should not ever have involved any maids. He chose instead to take a weak way out and to adopt the culture of the surrounding world in this instance. Make no mistake: he continues to be a man of incredible patience and faith, and rectitude in every other respect, but in this he did not do the right thing. Yet God in his providence does take his sons, and make them the founders of the tribes of Israel. If Jacob had done the right thing, then God would have had another course, but we cannot look into that. God, in his great goodness used Jacob’s sons, but Jacob had to pay a heavy price for this compromise: all the suffering in the family because Leah was so jealous of Rachel, because Jacob loved her. The one thing he should not have done is to carry on in a polygamous relationship, saying I cannot do without Rachel. His love comes before his obedience.
