Explanation

(a) 1 Kings 19:1-18

(i) Ahab told Jezebel all that Elijah had done and how he had killed all the prophets with the sword.

(ii) Jezebel sent to Elijah threatening to kill him as he had killed the prophets.

(iii) Elijah became afraid and fled to Beersheba, and left his servant behind.

(iv) He wandered alone into the wilderness and sat under a broom tree.

(v) He asked that he might die, asking God to take his life, for he was not better than his fathers.

(vi) As he slept under the broom tree, an angel touched him, saying, "Arise and eat".

(vii) He was fed with cake and water.

(viii) The angel woke him the second time to eat because his journey would be too great for him.

(ix) He ate and drank, and, by the strength of that food, travelled 40 days and 40 nights to Mount Horeb.

(x) On Horeb, he lodged in a cave and when the Lord asked him, what he was doing in the cave.

(xi) Elijah said he was jealous for God, for Israel had forsaken God's covenant, thrown down God's altars, killed His prophets, and he alone was left, yet they sought to kill him.

(xii) Elijah was asked to go and stand upon the mount before God.

(xiii) Here, he witnessed a great and strong wind, earthquake, fire and then a still small voice.

(xiv) On hearing the voice, Elijah wrapped his face in his mantle and stood at the mouth of the cave.

(xv) For the second time, a voice queried why he was there; he replied as before.

(xvi) God ordered him to return to the wilderness of Damascus.

(b) Ways God planned to punish the house of Ahab:

(i) In the wilderness of Damascus, Elijah would anoint Hazael king over Syria.

(ii) He would anoint Jehu to be King of Israel.

(iii) He would anoint Elisha to succeed him as prophet.

(iv) Whoever escapes from the sword of Hazael, Jehu should kill.

(v) Yet God would save 7000 in Israel, all those who had not bowed to Baal and those who had not kissed him.
