Leviticus 25:20-22

Leeser(i) 20 And if ye should say, What shall we eat in the seventh year? behold, we are not permitted to sow, and we cannot gather in our harvest: 21 Then will I command my blessing unto you in the sixth year, and it shall bring forth a harvest for three years. 22 And when ye sow in the eighth year, then shall ye eat yet of the old harvest; until the ninth year, until its harvest come in, shall ye eat of the old store.
