Isaiah 7:21-25

7:21 At that time a man will keep alive a young cow from the herd and a couple of goats. 7:22 From the abundance of milk they produce, he will have sour milk for his meals. Indeed, everyone left in the heart of the land will eat sour milk and honey. 7:23 At that time every place where there had been a thousand vines worth a thousand shekels will be overrun with thorns and briers. 7:24 With bow and arrow men will hunt there, for the whole land will be covered with thorns and briers. 7:25 They will stay away from all the hills that were cultivated, for fear of the thorns and briers. Cattle will graze there and sheep will trample on them.

Leviticus 25:4-5

25:4 but in the seventh year the land must have a Sabbath of complete rest – a Sabbath to the Lord. You must not sow your field or prune your vineyard. 25:5 You must not gather in the aftergrowth of your harvest and you must not pick the grapes of your unpruned vines; the land must have a year of complete rest.

Leviticus 25:20-22

25:20 If you say, ‘What will we eat in the seventh year if we do not sow and gather our produce?’ 25:21 I will command my blessing for you in the sixth year so that it may yield the produce for three years, 25:22 and you may sow the eighth year and eat from that sixth year’s produce – old produce. Until you bring in the ninth year’s produce, you may eat old produce.
