1 Samuel 14:39, 45

I vow by the name of the LORD who rescued Israel that the sinner will surely die, even if it is my own son Jonathan!” But no one would tell him what the trouble was.

But the people broke in and said to Saul, “Jonathan has won this great victory for Israel. Should he die? Far from it! As surely as the LORD lives, not one hair on his head will be touched, for God helped him do a great deed today.” So the people rescued Jonathan, and he was not put to death.
