cheftze: the Shev Shematzah (same author as the Ketzos) He said them at his sheva brachos.
From BaalHabooze(Dvar Torah Thread): Here's another beauty.
The gemorah learns out you can marry a woman with money from the gezeira shova from our parsha:" כּסף מנלן? ....קיחה קיחה משׂדה עפרון."
The troubling aspect with this is, why not say it straight out! Why send us to the story of Efroin, where Avrohom bought land from him, why does the torah make us read about this greedy conceited man Efroin, I mean, my gosh, do we really have to come on to HIM to learn out money can be used for marriage?? Say it out:ויקח אישׁ אשׁה בּכּסף (ובּשׁוה כּסף)!
The answer is that we see something interesting by that meeting, from BOTH parties involved. Efroin thought he's getting the deal of the century by selling this dark old cave for a clearly overpriced cost. Avrohom was more than delighted to pay for this burial plot which Odom and Chava were buried in. Each one beleived HE got the better end of the deal! AND THAT'S HOW PEOPLE SHOULD ENTER A MARRIAGE!!! Both the chosson and the kalla should look each other in the eye and think to themself, Wow I can't beleive my fortune! I won the lottery! My bashert is the greatest thing ever, I can't beleive how lucky I am!
Now, go use this vort by your next sheva brochos :)
