'Yet' in the Bible

yet knowing that a man is not justified by the works of the law but through faith in Jesus Christ, even we believed on Christ Jesus, that we might be justified by faith in Christ, and not by the works of the law: because by the works of the law shall no flesh be justified.

Brethren, I speak after the manner of men: Though it be but a man's covenant, yet when it hath been confirmed, no one maketh it void, or addeth thereto.
