Do not lost big due to small loss

1 Kings 2:36-46
Shimei, another potential troublemaker, is put on parole (言語) in Jerusalem to keep his away from fellow-Benjamites. When he breaks parole, even through for an innocent reason, Solomon has him killed.
Solomon killed Shimei for he did to David. Now the Lord will repay him for his wrongdoing.
Why?
Shimei lost life for searching his two slaves.
What is the first priority in our life? What needs to do first?
Do not lost big due to small loss.
How?
Dear Lord! Please give me wisdom and build the priority in my life, give me the capability to make right decision.
