'Mistake' in the Bible

And take double [the] money in your hands. Take back the money that was returned in the mouth of your sacks. Perhaps it [was] a mistake.

Then Saul said, "I have sinned! Come back, David my son, for I will not harm you again, because my life [was] precious in your eyes this day. Look, I have acted like a fool and {have made a terrible mistake}."

Do not let your mouth lead your flesh into sin, and do not tell the messenger that it [was] a mistake. Why anger God at your words, so that he destroys the work of your hands?

that {you have made a fatal mistake}, for you sent me to Yahweh your God, {saying}, 'Pray for us to Yahweh our God, and all that Yahweh our God says, so tell us and we will do [it].'
