'Indeed' in the Bible

For even if there are "gods" in heaven and on earth (as indeed there are many so-called "gods" and "lords"),

For the person who speaks in a foreign language is not actually speaking to people but to God. Indeed, no one understands him, because he is talking about secrets by the Spirit.

Indeed, brothers, if I come to you speaking in foreign languages, what good will I be to you unless I speak to you in some revelation, knowledge, prophecy, or teaching?

This, indeed, is what is written: "The first man, Adam, became a living being." The last Adam became a life-giving spirit.

in a moment, faster than an eye can blink, at the sound of the last trumpet. Indeed, that trumpet will sound, and then the dead will be raised never to decay, and we will be changed.
