His words are consistent and true forever

2 Kings 8:7-29
Elisha fulfills God's commission to Elisha(1 kings19:15) - Hazael king over Aram.
Hazael, like Macbeth, resorts to murder to turn prediction into face and seize the throne.
Elisha began to weep for he knew that Hazael will harm to the Israelites.
The deception is presumably intended to give the king a false sense of security and enable Hazael to take the throne on his death. But he is not prepared to wait.
Jehoram was a bad king in Judah, influenced by his wife Athaliah, daughter of Ahab and Jezebel. Ahaziah was another king who turned from God and went his won way. He reigned only one year.
For the sake of his servant David, The Lord was not willing to destroy Judah. He had promised to maintain a lamp for David and his descendants forever.
Why?
Elisha said the same words of God as the Lord said to Elijah before Elisha be anointed as prophet.
Elisha love Israelites, although he knew what will be in Israel. So he wept for the Israelites.
Kings of Judah did bad king- did not walk in the way of the Lord, for the sake of David, it is the promise of the Lord, so Judah exists. The promise of the Lord to David and his descendants is the future kingdom of Jesus.
Marriage is influence to the living style, someone's marriage is rely on the relationship of social or on the property. The good marriage is based on the love between each other and good helper to him.
How?
The words of the Lord are consistent and never fail.
