Daily Aliya for Bechukotai, Chamishi (5th Aliya)
Aliya Summary: This Aliya discusses the endowment of land to the temple. If it is land which was part of the family lot (given to his ancestors when Israel was divided amongst the Tribes), then the redemption price is a fixed amount, depending on its harvest yield. If the owner chooses not to redeem it, it may be redeemed by any other individual. In this event, or if the land remains unredeemed, the land becomes the property of the priests during the next Jubilee year.
Redeeming a previously endowed piece of land, one must had a fifth as a penalty. Perhaps it’s to cover the paperwork associated with donating and then undoing the donation and replacing it with cash? Either way, it pays to think it through before exercising such options.
