His words is everlasting.

2 Kings 6:24-7:20
Famine in besieged Samaria was severe for Aram monilized his entire army.
The king of Israel heard the story of two women ate their sons for life, he tore his robes, had sackcloth on his body.
King of Israel knew "If the Lord does not help you, where can I get help for you?"
Elisha said to elders "Don't you see how this murder is sending someone to cut off my head? The king of Israel said to Elisha "This disaster is from the Lord. Why should I wait for the Lord any longer?"
Elisha said the words of the Lord to king, the office on whose arm the king was leaning said to the man of God,"Look,even if the Lord should open the floodgates of the heavens could this happen?" t
Their desperate hunger make them the first to discover the truth of Elisha's prediction.
"You will see it with your own eyes," answered Elisha, "but you will not eat any of it!"
The Aramean arm ran for their lives one night, as the Lord had said and it is exactly what happened to the office.
Donkey sold for 1 kg silver and 0.3 liter seed for 55 gram silver. After relive of besieged, flour of 7.3liters sold 11 gram silver, 15 liters of barley sold 11 gram silver.
Why?
The peace secured by Elisha does not last for ever.
People always complain to the Lord when they suffered some disaster, the king of Israel humbled himself and went to see the prophet Elisha is the key to solve his problem.
Under any situation the Lord is our helper and savior.
How?
Knowing God and worshiping the Lord , praying to the Lord is because the Lord loves us. His words is everlasting.
