Adam Clarke on 1 Samuel 14:45

And the people said - "Shall Jonathan die, who hath wrought this great salvation in Israel? God forbid! As the Lord liveth, there shall not one hair of his head fall to the ground." Here was a righteous and impartial jury, who brought in a verdict according to the evidence: No man should die but for a breach of the law of God; but Jonathan hath not broken any law of God; therefore Jonathan should not die. And because he should not, therefore he shall not.

He hath wrought with God this day - God has been commander-in-chief; Jonathan has acted under his directions.

So the people rescued Jonathan - And God testified no displeasure; and perhaps he permitted all this that he might correct Saul's propensity to rashness and precipitancy.
