Verse 15. - And Elijah said, As the Lord of hosts liveth, before whom I stand [This formula should be compared with that of 1 Kings 17:1. The repetition is suggestive as exhibiting the habit of the man. He was the ready and patient slave of Jehovah. The צְבָאותis apparently introduced not so much to "elevate the solemnity of the oath" (Keil, Bahr) - for surely Elijah would wish to make the affirmation of 1 Kings 17:1 as strong and solemn as possible - nor yet to convey the meaning that "it is not Baal or Ashtaroth who are the rulers of the heavenly bodies" (Wordsworth), for Obadiah knew that perfectly well, but because it was thus better adapted for a believer. In addressing Ahab it suited Elijah's purpose better to give prominence to the idea that Jehovah was "the God of Israel"], I win surely show myself unto him today.

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.And Elijah said, as the Lord of hosts liveth, before whom I stand,.... In whose presence he was, and whose prophet and minister he was; he takes this oath, to assure Obadiah that he would certainly be upon the spot, or to be found, and not expose him to any danger:

I will surely show myself unto him today; he was determined at all events to present himself to him that day.
