Arameans, they made peace with David and became subject to him.

1 Chronicles 19:1-19
In the course of time, Nahash king of the Ammonites died, and his son succeeded him as king. David sent a delegation to express his sympathy to Hanun concerning his father.
The Ammonite commanders said to Hanun, “Do you think David is honoring your father by sending envoys to you to express sympathy? Haven’t his envoys come to you only to explore and spy out the country and overthrow it?” So Hanun seized David’s envoys, shaved them, cut off their garments at the buttocks, and sent them away.
Abishai his brother, and they were deployed against the Ammonites. Joab said, “If the Arameans are too strong for me, then you are to rescue me; but if the Ammonites are too strong for you, then I will rescue you.
Then Joab and the troops with him advanced to fight the Arameans, and they fled before him. When the Ammonites realized that the Arameans were fleeing, they too fled before his brother Abishai and went inside the city. So Joab went back to Jerusalem.
When the vassals of Hadadezer saw that they had been routed by Israel, they made peace with David and became subject to him. So the Arameans were not willing to help the Ammonites anymore.
Why?
The misunderstanding may cause a war between the two nations, so as among men.
Abishai and Joab worked together they fight against enemy on both sides and rescue each other when they needed. For the Lord is with Israel so they defeated Ammonites.
When we walking with the Lord, God's blessing is stronger than any other weapon or man.

哈嫩不領情且做愚昧的事！向大衛示威。其實對他沒有一點好處。人往往逞一時只快，種下禍因，造成更大損失。
約押在此說了重要的話。剛強做大丈夫。為神的律法，百姓衷心，為神的城，顯出他們之間是生命的關係。不是為己！亞蘭人與亞捫人是因利益而結盟。誰願意為對方捨命呢？只求對方的好處，不求自己的益處，是與神立約的基礎。
教會所行都如我意就認為教會好。如果不如己意，可能教會有問題，更多是我們自己有問題。神與人用什麼建立關係，是用愛與生命建立關係。
這場戰爭原來與亞蘭人無關，卻為了利益與面子。輸的更大，神叫人失敗是要人悔改。
How?
Let follow the way of the Lord and humble ourselves to honor God's holy name. The Lord is my shepherd and is my blessing.
