Not serve kings but serve the Load

I Samuel 19:1-17
Saul told his son and all the attendants to kill David.
Johnathan spoke well of David to Saul his father. Saul than took this oath: "As sure as the Load lives, David will not be put to dead." So Johnathan brought David to Saul, and David was with Saul as before.
But an evil spirit from the Load came upon Saul as he was sitting in his house with his spear in hand. While David was playing the harp, Saul tried to pin him to the wall with his spear, but David eluded and made good his escape that night.
Michal, his wife, warned David, and help David run away for his life, Michal let David down through a window. Michal deceived his father said David is ill. Michal saved David's life.
Only Saul want to kill David, all others were tried to protect David.
Why?
Saul had mental disorder, he forgot what he has promised and jealous. David didn't ill but Saul was ill.
David eluded for the Load is with him.
David served a ill king, so he have to care his life and make good escape.
How?
We do our best to serve our boss or king, but when the king or boss are ill or mental disorder, even could hurt us, we have to care and make good escape. Our honest is to the Load.
