Deuteronomy 11:13

"And it shall come to pass, if ye shall hearken diligently unto my commandments which I command you this day, to love Jehovah your God, and to serve him with all your heart and with all your soul, that I will give the rain of your land in its season, the former rain and the latter rain, that thou mayest gather in thy grain, and thy new wine, and thine oil. And I will give grass in thy fields for thy cattle, and thou shalt eat and be full. Take heed to yourselves, lest your heart be deceived, and ye turn aside, and serve other gods, and worship them; and the anger of Jehovah be kindled against you, and he shut up the heavens, so that there shall be no rain, and the land shall not yield its fruit; and ye perish quickly from off the good land which Jehovah giveth you."

"The former rain ... the latter rain ..." (Deuteronomy 11:14). The former rains came from the middle of October to the end of December, and the latter rains came in March and April."[11] The failure of either of these seasonal rains was a very serious impediment to the production of crops. On the other hand, God's generosity to Israel in the unusual fertility of the land of Canaan at that time, along with its plentiful rainfall at appropriate times, might be a source of temptation to Israel to believe that, "The fertility was due to Baal, the god of the land (as in the customs and beliefs of the Canaanites)."[12] We like Moffatt's rendition of this warning, "Beware of letting yourselves be fooled!" (Deuteronomy 11:16).

These verses make agricultural blessings to be CONTINGENT absolutely upon the blessing of Almighty God, and Scott, commenting on this said:

"After all, there is truth in the saying that sound morality and true religion are good economics. `Seek ye first his kingdom and his righteousness; and all these things shall be added unto you (Luke 12:31).' The position of Deuteronomy is very similar. Reverence and love Jehovah for what He is; put His laws into daily practice, and it shall be well with thee."[13]
