And it came to pass after many days, that the word of the LORD came to Elijah in the {a} third year, saying, Go, shew thyself unto Ahab; and I will send rain upon the earth.

(a) After that he departed from the river Cherith.

Wesley's Notes

18:1 The third year - Either, From the time when he went to hide himself by the brook Cherith; six months before which time the famine might begin. And so this being towards the end of the third year, it makes up these three years and six months, James 5:17. Or, From the time of his going to Sarepta, which probably was a year after the famine begun; So this might be in the middle of the third year, which also makes up the three years and six months. Go to Ahab - To acquaint him with the cause of this judgment, and to advise him to remove it, and upon that condition to promise him rain. Will send - According to thy word and prayer, which thou shalt make for it. Thus God takes care to maintain the honour of his prophet, and in judgment remembers mercy to Israel, for the sake of the holy seed yet left among them, who suffered in this common calamity.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 18

1Ki 18:1-16. Elijah Meets Obadiah.

1. the third year-In the New Testament, it is said there was no rain "for the space of three years and six months" [Jas 5:17]. The early rain fell in our March, the latter rain in our October. Though Ahab might have at first ridiculed Elijah's announcement, yet when neither of these rains fell in their season, he was incensed against the prophet as the cause of the national judgment, and compelled him, with God's direction, to consult his safety in flight. This was six months after the king was told there would be neither dew nor rain, and from this period the three years in this passage are computed.

Go, show thyself unto Ahab-The king had remained obdurate and impenitent. Another opportunity was to be given him of repentance, and Elijah was sent in order to declare to him the cause of the national judgment, and to promise him, on condition of his removing it, the immediate blessing of rain.

Matthew Henry's Concise Commentary

18:1-16 The severest judgments, of themselves, will not humble or change the hearts of sinners; nothing, except the blood of Jesus Christ, can atone for the guilt of sin; nothing, except the sanctifying Spirit of God, can purge away its pollution. The priests and the Levites were gone to Judah and Jerusalem, 2Ch 11:13,14, but instead of them God raised up prophets, who read and expounded the word. They probably were from the schools of the prophets, first set up by Samuel. They had not the spirit of prophecy as Elijah, but taught the people to keep close to the God of Israel. These Jezebel sought to destroy. The few that escaped death were forced to hide themselves. God has his remnant among all sorts, high and low; and that faith, fear, and love of his name, which are the fruits of the Holy Spirit, will be accepted through the Redeemer. See how wonderfully God raises up friends for his ministers and people, for their shelter in difficult times. Bread and water were now scarce, yet Obadiah will find enough for God's prophets, to keep them alive. Ahab's care was not to lose all the beasts; but he took no care about his soul, not to lose that. He took pains to seek grass, but none to seek the favour of God; fencing against the effect, but not inquiring how to remove the cause. But it bodes well with a people, when God calls his ministers to stand forth, and show themselves. And we may the better endure the bread of affliction, while our eyes see our teachers.
