Interesting that H4191 is twice, meaning exponential emphasis.
I found ISR wasn;t consistant in applying "ban" since used elsewhere with other words.

FWIW: My take on it, since instructions regarding Jubilee year, especially v29 is anyone facing capital punishment for crimes is not released...maybe even their land forfeited....but I'm not sure since haven't delved into and understand all that occurs during jubilees, real and metaphorical.

Also seems Jubilees were God's way of preventing debt buildup/collapse/depressions, which tend to run about evey 50 years thruout history...even with honest weights and measures (real money, not faith based fiat currency).

I seem to recall that Yah based the Babylonian exile on their failure to obeserve Jubilees... You didn't observe for xxx years so you'll be exiled for that long.
