'Aware' in the Bible

Or if anyone swears [an oath] thoughtlessly or impulsively aloud that he will do either evil or good, in whatever manner a person may speak thoughtlessly or impulsively with an oath, but he is unaware of it, when he recognizes it, he will be guilty in one of these.

“Now if anyone sins and does any of the things which the Lord has forbidden, though he was not aware of it, still he is guilty and shall bear his punishment.
