If you promise part of your family's land to me, its value must be determined by the amount of seed needed to plant the land, and the rate will be ten pieces of silver for every twenty kilogrammes of seed.
If you promise me a donkey, you may buy it back by adding an additional twenty per cent to its value. If you don't buy it back, it can be sold to someone else for whatever a priest has said it is worth.
In addition, you must pay what you owe plus a fine of twenty per cent. Then the priest will offer the ram as a sacrifice to make things right, and you will be forgiven.
