'Foolishly' in the Bible

You didn't even allow me to kiss my daughters and my grandchildren good-bye. You have acted foolishly!

So Aaron said to Moses, "O my lord, please do not hold this sin against us, in which we have acted foolishly and have sinned!

Saul replied, "I have sinned. Come back, my son David. I won't harm you, for you treated my life with value this day. I have behaved foolishly and have made a very terrible mistake!"

David felt guilty after he had numbered the army. David said to the Lord, "I have sinned greatly by doing this! Now, O Lord, please remove the guilt of your servant, for I have acted very foolishly."

David said to God, "I have sinned greatly by doing this! Now, please remove the guilt of your servant, for I have acted very foolishly."

Certainly the Lord watches the whole earth carefully and is ready to strengthen those who are devoted to him. You have acted foolishly in this matter; from now on you will have war.

If you have done foolishly by exalting yourself or if you have planned evil, put your hand over your mouth!

I thought deeply about the effects of indulging myself with wine (all the while my mind was guiding me with wisdom) and the effects of behaving foolishly, so that I might discover what is profitable for people to do on earth during the few days of their lives.
