'Conscious' in the Bible

And having become clearly conscious in himself, he came to the house of Mary, the mother of John who was surnamed Mark, where were many gathered together and praying.

And Paul said, I was not conscious, brethren, that he was high priest; for it is written, Thou shalt not speak evilly of the ruler of thy people.

For I am conscious of nothing in myself; but I am not justified by this: but he that examines me is the Lord.
