'Conscious' in the Bible

Is it not now the time of the grain cutting? My cry will go up to the Lord and he will send thunder and rain: so that you may see and be conscious of your great sin which you have done in the eyes of the Lord in desiring a king for yourselves.

So David took the spear and the vessel of water from Saul's head; and they got away without any man seeing them, or being conscious of their coming, or awaking; for they were all sleeping because a deep sleep from the Lord had come on them.

And Saul, conscious that the voice was David's, said, Is that your voice, David, my son? And David said, It is my voice, O my lord king.
