But in the seventh year there shall be a Sabbath of complete rest for the land--a Sabbath to the LORD. You are not to sow your field or prune your vineyard.

Leviticus 25:5
You are not to reap the aftergrowth of your harvest or gather the grapes of your untended vines. The land must have a year of complete rest.

Leviticus 25:20
Now you may wonder, 'What will we eat in the seventh year if we do not sow or gather our produce?'

2 Chronicles 36:21
So the land enjoyed its Sabbath rest all the days of the desolation, until seventy years were completed, in fulfillment of the word of the LORD through Jeremiah.

But in the seventh year shall be a sabbath of rest to the land, a sabbath for the LORD: you shall neither sow your field, nor prune your vineyard.
