There are two intriguing commentaries, each relating to a different posuk of Parsha Chaye Sarah, regarding the dialogue leading up to Avraham Aveinu’s acquisition of the Ma’arat HaMachpela for 400 shekels of silver from Efron the Hittite.
The first of the two posukim is spoken by Avraham and says, in part, “I will have given the money for the field; take it of me …” (Breish’it, Perek 23, posuk 13)
“…That a man may marry a woman by using money to effect the marriage is deduced in the Talmud (Kiddushin 2) by drawing a parallel from this verse. But the parallel goes beyond merely the acquisition of the land of the Efronite and the acquisition of a wife. Just as in a marriage the act of acquisition is only the beginning and not the end, because that is when all one’s obligations begin — food, clothing, etc. — the same is true in our dealings with the Efronites. Nothing ends with written contracts and agreements. We pay, pay and pay again, and yet they keep demanding more from us.” (Torah Gems on Chaye Sarah, page 182 quoting Rabbi A.M. Amiel) [...]
