'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.

Then Saul said, I have done wrong: come back to me, David my son: I will do you no more wrong, because my life was dear to you today truly, I have been foolish and my error is very great.
