Leviticus 26:2-5

2Ye shall observe my sabbaths, and my sanctuary shall ye reverence: I am Jehovah.

3If ye walk in my statutes, and observe my commandments and do them,

4then I will give your rain in the season thereof, and the land shall yield its produce, and the trees of the field shall yield their fruit;

5and your threshing shall reach unto the vintage, and the vintage shall reach unto the sowing-time; and ye shall eat your bread to the full, and dwell in your land securely.
