The Gemara in Kiddushin (2b) connects and learns many laws of marriage from Avraham’s purchase of the Cave of Machpayla from Efron. Regarding marriage and regarding this purchase it states the word, “קיחה”. What do the two have to do with each other? What is the depth here?
I once heard a beautiful explanation from a friend of mine. Avraham purchased this priceless holy burial plot from Efron. Knowing its spiritual value, he was willing to pay any price for it. Efron was a money hungry greedy person who wanted all the money he could get. They worked out an astronomical price and Avraham paid it on the spot.
Now, if you were to ask either of them, who got the better end of the deal, each would say they did. Avraham would say, “to be able to buy this priceless lot is a gift to me from Hashem”! Efron would say, “this worthless lot made me amazingly rich”!
So too should be the perspective of the Bride and Groom. Each one should say,
“I’m the luckiest person in the world to have gotten you as my spouse”!
