And you shall spend the money for whatever your soul desires—for oxen or for sheep or for wine or for strong drink or for whatever your soul asks of you—and you shall eat there before Hashem your God and you shall rejoice, you and your household.
English: "And you shall give the money" — One who exchanges a sela of ma’aser-sheni coins: Beis Hillel say he exchanges half in silver and half in copper. From where do we know that a second exchange is permitted? From the verse "and you shall give the money," which includes even a second silver.
On the daf / in context: When changing copper ma’aser coins into silver one should leave half in copper so that the money-changers in Yerushalayim will not inflate the price of small change.
