'Error' in the Bible

And all the people were with Saul, about twenty thousand men, and the fight was general through all the hill-country of Ephraim; but Saul made a great error that day, by putting the people under an oath, saying, Let that man be cursed who takes food before evening comes and I have given punishment to those who are against me. So the people had not a taste of food.

Saul responded, “I have sinned. Come back, my son David, I will never harm you again because today you considered my life precious. I have been a fool! I’ve committed a grave error.”
