'Indeed' in the Bible

Have ye suffered so many things in vain, if indeed also in vain?

Is then the law against the promises of God? Far be the thought. For if a law had been given able to quicken, then indeed righteousness were on the principle of law;

But then indeed, not knowing God, ye were in bondage to those who by nature are not gods;

I am afraid of you, lest indeed I have laboured in vain as to you.
