Mission of the Lord is keep going on

1 Kings 19:15-21
The Lord said to Elijah,"Go back the way you came, and go to the Desert of Damascus. Anoint Hazael king over Aram. Also, anoint Jehu son of Nishi king over Israel, and anoint Elisha son of Shaphat from Abel Meholah to succeed you as prophet."
"Yet I reserved seven thousand in Israel - all whose knees have not bowed down to Baal and all whose mouths have not kissed him."
Elijah went up to Elisha and threw his cloak around him. Elisha then left his oxen and ran after Elijah. "Let me kiss my father and mother good-by," he said," and then I will come with you."
Elijah had left himself intolerably(難以忍受) alone, his work finished. He is given a companion and successor, Elisha. God's work goes on.
Elisha is "anointed", called to become a prophet, by Elijah's symbolic action in throwing his cloak around him. But the anointing of Hazael and Jehu is left to Elisha.
7000 men: The number is probably symbolic: 7(for perfection)* 1000.
Why?
God asked Elijah go back to the land he had escaped, and had new missions, to anoint new kings. And anoint his successor, Elisha.  God recover Elijah faith and strength. God encouraged Elijah, he is not alone, there are 7000 men belong to the Lord in Israel.
Even Elijah was tired and Elisha succeed him as prophet. God's work keep going on. Never stop by man's any situation happened.
Elisha said good-bye to his parent then became Elijah's attendant. It is the procedure to be a God's servant. It is not to get the permission from parent, but let parent know where I will go.
How?
Every kings in the world is anointed by the Lord, God recovered the faith of Elijah, his servant. The Lord will recover me when I serving the  Lord!
