1st Kings 17:5 So he went and did according unto the word of the Lord: for he went and dwelt by the brook Cherith, that is before Jordan. 7 And it came to pass after a while, that the brook dried up, because there had been no rain in the land.
[Prophets & Kings pp 124] God's message to Ahab gave Jezebel and her priests and all the followers of Baal and Ashtoreth opportunity to test the power of their gods, and, if possible, to prove the word of Elijah false. Against the assurances of hundreds of idolatrous priests, the prophecy of Elijah stood alone. If, notwithstanding the prophet's declaration, Baal could still give dew and rain, causing the streams to continue to flow and vegetation to flourish, then let the king of Israel worship him and the people say that he is god.
Determined to keep the people in deception, the priests of Baal continue to offer sacrifices to their gods and to call upon them night and day to refresh the earth. With costly offerings the priests attempt to appease the anger of their gods; with a zeal and a perseverance worthy of a better cause they linger round their pagan altars and pray earnestly for rain. Night after night, throughout the doomed land, their cries and entreaties arise. But no clouds appear in the heavens by day to hide the burning rays of the sun. No dew or rain refreshes the thirsty earth. The word of Jehovah stands unchanged by anything the priests of Baal can do.
A year passes, and yet there is no rain. The earth is parched as if with fire. The scorching heat of the sun destroys what little vegetation has survived. Streams dry up, and lowing herds and bleating flocks wander hither and thither in distress. Once-flourishing fields have become like burning desert sands, a desolate waste. The groves dedicated to idol worship are leafless; the forest trees, gaunt skeletons of nature, afford no shade.
1st Kings 18:2 And Elijah went to shew himself unto Ahab. And there was a sore famine in Samaria.
May God add His blessing to the study of His word. “Good might” and God bless!
