'Presumptuously' in the Bible

The man who acts presumptuously and insolently by not listening to the priest who stands there to serve the Lord your God, nor to the judge, that man shall die; so you shall remove the evil from Israel.

Then all the people will hear and be afraid, and will not act presumptuously again.

When a prophet speaks in the name of the Lord and the thing does not happen or come true, that is the thing which the Lord has not spoken. The prophet has spoken it presumptuously; you shall not be afraid of him.
