Jubilee

Jubilee is the name of the great semi-centennial festival of the Hebrews. It lasted for a year. During this year the land was to be fallow, and the Israelites were only permitted to gather the spontaneous produce of the fields (Lev. 25:11-12). All landed property during that year reverted to its original owner (Lev. 25:13-34; Lev. 27:16-24), and all who were slaves were set free (Lev. 25:39-54), and all debts were remitted.

Sounds like God already knew man wasn't going to be a good steward of his finances.
