'Idea' in the Bible

Was today the first time I inquired of God for him? Of course not! Please don’t let the king make an accusation against your servant or any of my father’s household, for your servant didn’t have any idea about all this.”

Remember, therefore, what you have received and heard; keep it, and repent. But if you are not alert, I will come like a thief, and you have no idea at what hour I will come against you.
