Erchin 8:2-3

Erchin 8:2

Let’s say that bidders for consecrated property bid 10, 20, 30, 40 and 50 sela, respectively. The one who bid 50 then retracted his offer. They then take ten sela in property from him (which, combined with the now-winning bid of 40, equals the 50 he had offered). If the one who bid 40 then retracted, they take ten sela in property from him as well (and the one who bid 30 becomes the new winner). If the one who bid 30 retracted, they take ten sela in property from him; if the one who bid 20 retracted, they take ten sela in property from him. If the one who bid 10 retracted, they sell the property for what it’s worth and take the difference from him. If the owner and another person both bid 20, the owner’s bid is accepted because he adds the extra fifth.

Erchin 8:3

If another person bid 21, the owner (who bid 20 plus the added fifth) must pay 26; if 22, he must pay 27; if 23, he must pay 28; if 24, he must pay 29; if 25, the owner must pay 30. In all of these cases, the owner does not add a fifth beyond what the other person outbid him. If another person bid 26 and the owner was willing to pay 31 plus a dinar, the owner gets it; if not, the other person wins the auction.
