“You shall count off seven weeks of years, seven times seven years, so that the period of seven weeks of years gives forty-nine years. Then you shall have the trumpet sound loud. On the ten day of the seventh month, on the Day of Atonement. You shall have the trumpet sounded throughout all your land. You shall hallow the fiftieth year. You shall proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee for you. You shall return, every one of you, to your property. Every one of you shall return to your family. That fiftieth year shall be a jubilee for you. You shall not sow or reap the after-growth of the harvest or the un-pruned vines. For it is a jubilee. It shall be holy to you. You shall eat only what the field itself produces.”
The Jubilee year comes every 50 years. 7 times 7 equal 49. After 7 Sabbath years, you shall have the trumpet sound loud on the 10th day of the 7th month, on the Day of Atonement. Thus the 50th year is a jubilee for you. Everyone returns to their family and their own property, with no sowing, reaping, or harvesting. You eat only what the field itself produces.
“In this year of jubilee you shall return, every one of you, to your property. When you make a sale to your neighbor or buy from your neighbor, you shall not cheat one another. When you shall buy from your neighbor, you shall pay only for the number of years since the jubilee. The seller shall charge you only for the remaining crop years. If the years are more, you shall increase the price. If the years are fewer, you shall diminish the price. It is a certain number of harvests that are being sold to you. You shall not cheat one another. But you shall fear your God. I am Yahweh your God. You shall observe my statutes, and faithfully keep my ordinances so that you may live on the land securely. The land will yield its fruit. You will eat your fill and live on it securely.”
What about transactions during this time? First all you do not cheat each other. You charge people based on how close it is to the jubilee year, since most people would know when it is coming. The price of the property and crops are based on jubilee year. If you fear God and observe his ordinances, you will live on the land securely.
