You weren't mixed up at all - the freeing of the slaves in their seventh year included the release of certain debts - some call it the "Little Jubilee".Thanks for the graceful correction. I had that mixed up with slaves being freed every 7 years
I went for a loan Friday and noticed a ball and chain in the corner. I asked how long I had to wear it. The loan officer said "Twenty years, and you have to pay separate fees for the ball and the chain, in advance." Kidding.
