2 Chronicles 10-12

But this word of the Lord came to Shemaiah the man of God: “Say to Rehoboam son of Solomon king of Judah and to all Israel in Judah and Benjamin,  ‘This is what the Lord says: Do not go up to fight against your fellow Israelites. Go home, every one of you, for this is my doing.’” So they obeyed the words of the Lord and turned back from marching against Jeroboam. (2 Chronicles 11:3-4)

Shemaiah is one powerful and courageous man of God. I suppose these qualities come from the conviction provided in the act of receiving a word from God. Rehoboam obeys. The fighting men turn back. War is averted, and a modicum of peace is forged between the two kingdoms. Still...

So Israel has been in rebellion against the house of David to this day. (1 Chronicles 10:19)

My nation has opposing political factions, too, and our citizens have warred against one another.
