Do whatever seems best to me but also best to the Load

I Samuel 14:36-52
Saul want to pursue the Philistine by night and ask Israelite stand over there and he and his son Jonathan stand over here. The Israelite said "Do whatever seems best to you"
The priest said "Let us inquire of God here"
When he found Jonathan ate a little honey, want to kill his son, the men said to Saul," Should Jonathan die- he who has brought about this deliverance in Israel! As sure as the Load lives, not a hair of this head will fall to the ground, for he did this today with God's help"
Saul stop pursuing the Philistines, Jonathan was not put to death.
Saul assumed rule over Israel, he fought valiantly and defeated the enemy of Israel.
Why?
Saul didn't know this deliverance in Israel brought by Jonathan is God's help, but the Israelite know this.
The priest in the key time said a correct word to the king, this is his responsibility. He saved Saul and Israelite from perish.
Most time the men have not idea in mind, they will say " Do what seems best to you". But if it is very obviously  wrong, the men will reply directly. And it is a powerful opinion.
The people intervene of his father's rash oath.
How?
To be a minister of the Load, I should say something that I have to say, it is relate to the righteousness and walk along the way of the Load.
I am tender with mercy , but I should be do the right thing.
