'Aware' in the Bible

"Haven't you heard?" Nathan asked Solomon's mother Bathsheba. "Haggith's son Adonijah has become king and David, our true king, isn't aware of it.

Now look, Adonijah has become king, and your majesty is not aware of it.

"Furthermore, you're aware of what Zeruiah's son Joab did to me and to those two commanders of the armies of Israel, Ner's son Abner and Jether's son Amasa, whom he killed, and how he shed the blood of wartime during times of peace, staining the very belt he wears around his waist and the sandals he wears on his feet.

The king of Israel asked his servants, "Were you aware that Ramoth-gilead belongs to us, but we aren't doing anything to remove it from the control of the king of Aram?"
