'Willfulness' in the Bible

‘If anyone sins after he hears a public adjuration (solemn command to testify) when he is a witness, whether he has seen or [otherwise] known [something]—if he fails to report it, then he will bear his guilt and be held responsible.

Since the days of our fathers to this day we have been exceedingly guilty; and on account of our wrongdoings we, our kings, and our priests have been handed over to the kings of the lands, to the sword, to captivity, to plundering, and to complete shame, as it is today.
