Leviticus 25:17-21

Ye shall not therefore oppress one another; but thou shalt fear thy God: for I am the LORD your God.

Wherefore ye shall do my statutes, and keep my judgments, and do them; and ye shall dwell in the land in safety.

And the land shall yield her fruit, and ye shall eat your fill, and dwell therein in safety.

And if ye shall say, What shall we eat the seventh year? behold, we shall not sow, nor gather in our increase:

Then I will command my blessing upon you in the sixth year, and it shall bring forth fruit for three years.
